OPINION AND ORDER
SHIRA A. SCHEINDLIN, District Judge.1. INTRODUCTION
Defendant Von Tucker has requested that this Court authorize a subpoena ordering the Bureau of Prisons to produce all recordings of telephone conversations involving each of the cooperating witnesses. The government has moved to quash the subpoena. For the reasons stated below, Tucker’s request is granted, the subpoena is issued with certain modifications, and the government’s motion is denied.1
II. BACKGROUND2
The government has stated its intention to call three cooperating witnesses to testify against Tucker. In connection with its obligation to disclose certain evidence, the government has provided Tucker with redacted excerpts of transcripts of one of the witness’s telephone calls, and Tucker has *60stated that those transcripts indicate that the cooperating witness may have been promised inducements for his testimony. The cooperating witnesses are incarcerated, and Tucker has requested a subpoena under Rule 17 of the Federal Rules of Criminal Procedure for recordings of all calls made by cooperating witnesses while incarcerated (the “Recordings”) so that he can gather information on possible inducements offered to those witnesses in exchange for their testimony. The government has disclosed that there are over forty-five hours of Recordings, and has moved to quash the subpoena on the ground that it exceeds the bounds of discovery permitted by the Federal Rules of Criminal Procedure.3
III. APPLICABLE LAW
A. Criminal Discovery
To determine the proper scope of a Rule 17(c) subpoena, it is useful to examine the structure of discovery in criminal cases to determine where such subpoenas best fit. The government’s ability to discover information is significantly broader than that of a defendant, although a defendant’s rights are protected by certain constitutional guarantees.
1. Investigation
The most obvious source of information for the prosecution is the investigatory arm of law enforcement. By the time the prosecution’s attention is drawn to an individual, law enforcement has typically gathered substantial evidence relating to the alleged offense. The government’s ability to gather evidence is further enhanced by the use of search and seizure, a mechanism not available to the defense.
Like the government, defendants can employ investigators to gather potential exculpatory evidence. However, an innocent defendant has no a priori knowledge of the accusations against which she must defend herself,4 and thus must rely on the government’s disclosures to calculate how best to present a defense.
2. Grand Jury
Grand jury proceedings provide another significant avenue for the prosecution to gather evidence.5 It is a “fundamental maxim” that the grand jury ‘“has a right to every man’s evidence____”’6 Before the grand jury, prosecutors have wide latitude to compel testimony and obtain documentary evidence without the restrictions imposed by the Federal Rules of Evidence and out of the presence of the defendant and her counsel.
Unlike the prosecution, the defendant has little or no access to grand jury proceedings. A defendant may not even be aware of a grand jury investigation until it is complete. Further, the Federal Rules of Criminal Procedure require that grand jury proceedings be kept confidential.7
*613. Constitutional Disclosure
The Constitution requires the prosecution to produce certain material to the defense. The most familiar requirement is the prosecution’s obligation to produce exculpatory evidence. In Brady v. Maryland, the Supreme Court held that the government’s failure to provide a defendant with exculpatory evidence in its possession violated the defendant’s constitutional rights.8 This obligation extends to evidence that a defendant can use to impeach the government’s witnesses.9
4. Discovery Authorized by Statute
The Jeneks Act provides that statements by government witnesses in the hands of the government must be produced, but not until after those witnesses have testified.10 Certain statutes provide some defendants with additional discovery. For example, defendants charged with capital offenses are entitled to a list of the witnesses against them at least three days before commencement of trial.11
5. Discovery Under the Federal Rules of Criminal Procedure
Rule 16 of the Federal Rules of Criminal Procedure requires that the parties disclose certain information.12 Upon request, the prosecution must provide certain statements made by the defendant; the defendant’s criminal record; access to certain physical evidence; and reports related to expert, scientific, and medical evidence.13 Significantly, the Rule does not require disclosure of statements made by government witnesses.14
Rule 26.2 of the Federal Rules of Criminal Procedure provides that after a witness testifies, a party may compel production of any relevant statements made by that witness. The Rule does not provide a method for discovery of statements or documents in the hands of a non-party even if they are relevant statements by a witness who has testified.
*62B. Rule 17(c) Subpoenas
Finally, there is Rule 17(c) of the Federal Rules of Criminal Procedure, which provides:
(1) In General. A subpoena may order the witness to produce any books, papers, documents, data, or other objects the subpoena designates. The court may direct the witness to produce the designated items in court before trial or before they are to be offered in evidence. When the items arrive, the court may permit the parties and their attorneys to inspect all or part of them.
(2) Quashing or Modifying the Subpoena. On motion made promptly, the court may quash or modify the subpoena if compliance would be unreasonable or oppressive.15
Rule 17(c) was adopted as part of the Federal Rules of Criminal Procedure in 1944 and has not been amended. The Advisory Committee Note states that “[t]his rule is substantially the same as rule 45(b) of the Federal Rules of Civil Procedure,”16 which permits parties in a civil action to obtain discovery from non-parties by way of a subpoena. This brief overview may indicate that the rule drafters initially thought Rule 17(c) would govern discovery from non-parties, while Rule 16 would govern discovery from the Government.
I. Cases Addressing Rule 17(c)
In Bowman Dairy v. United States, the Supreme Court held that it was permissible for a criminal defendant to issue a Rule 17(c) subpoena to the government, but that because Rule 16 obligates the government to disclose certain material to the defendant, the defendant’s Rule 17(c) subpoena could not exceed the scope of Rule 16.17 The Court thus determined that “Rule 17(c) was not intended to provide an additional means of discovery.”18 Instead, the Court explained that it provides a method “to expedite the trial by providing a time and place before trial for the inspection of subpoenaed materials.”19 Further, the subpoenas could be used only to discover material that could be considered “evidentiary.”20
In United States v. Nixon, the government sought to obtain records from a non-party, specifically the President of the United States, by means of a Rule 17(c) subpoena.21 Although Rule 17(c) provides only that the court may quash a subpoena “if compliance would be unreasonable or oppressive,”22 the Supreme Court adopted the four-part test set forth in United States v. Iozia for determining when a Rule 17(e) subpoena can be used.23 The Court summarized this test as “(1) relevancy; (2) admissibility; (3) specificity.”24 “If the moving party cannot reason*63ably specify the information contained or believed to be contained in the documents sought but merely hopes something useful will turn up, the requirement of specificity will not have been met.”25 The Court found that under this standard, the government’s subpoena would not be quashed.26
2. Subpoenas Issued by Defendants
“A criminal prosecution ... is in no sense a symmetrical proceeding.”27 It is inherent in our criminal justice system that defendants will virtually always be outmatched in investigatory resources, funds, and time to prepare for litigation. This does not offend the Constitution. “The Bill of Rights does not envision an adversary proceeding between two equal parties.”28 The principle of equality of arms may apply in certain international criminal law contexts,29 but it has no place in our constitutional jurisprudence.30 For better or worse, due process demands only that a criminal defendant receive a constitutionally “adequate” defense, not that the parties to a criminal prosecution be equally matched.31
As discussed above, the government has far more opportunity to obtain evidence than does a criminal defendant. The government can use grand jury subpoenas to obtain evidence, and the Supreme Court has held that “the Nixon standard does not apply in the context of grand jury proceedings----”32 Further, where the desired material is in the hands of an agency that has a close working relationship with the government, the government may be able to obtain the material simply by informal request.33
It is therefore fair to ask whether it makes sense to require a defendant seeking to obtain material from a non-party by means of a Rule 17(c) subpoena to meet the Nixon stan*64dard.34 In fact, several commentators argue that the standard is inappropriate.35 Unlike the government, the defendant has not had an opportunity to obtain material from non-parties either through a grand jury subpoena or through Rule 16 discovery (which only applies to parties).
A federal defendant’s opportunities for discovery are severely constrained.36 While in recent years state criminal law has moved to expand discovery opportunities for defendants,37 a federal criminal defendant’s ability to conduct discovery has not been re-examined.38
That the government has more opportunities to gather evidence is not in itself a reason to expand defendants’ rights. “[I]n the context of criminal investigation and criminal trials, where accuser and accused have inherently different roles, with entirely different powers and rights, equalization is not a sound principle on which to extend any particular procedural device.”39
“But, the Constitution recognized the awesome power of indictment and the virtually limitless resources of government investigators. Much of the Bill of Rights is designed to redress the advantage that inheres in a *65government prosecution.”40 Therefore, in determining whether a right should be afforded to a criminal defendant in the absence of a legislative command, the issue is whether the Constitution requires that right.
Criminal defendants have the right to “put before a jury evidence that might influence the determination of guilt.”41 To effect this right, a defendant must have the ability to obtain that evidence.
Determining whether a defendant’s subpoena should be quashed thus requires an assessment of the extent to which the subpoena is necessary to permit the defendant to raise a defense. Generally, this is accomplished through the Nixon test of “(1) relevancy; (2) admissibility; (3) specificity,”42 and indeed, a number of courts have applied the Nixon standard to defense subpoenas without analysis.43 Because of the requirement of specificity, Nixon makes clear that a Rule 17(c) subpoena may not be used for a “general fishing expedition.”44
3. Subpoenas Issued to a Non-Party
A party may issue subpoenas to another party and to a non-party. In Bowman Dairy v. United States, the Supreme Court held that it was permissible for a criminal defendant to issue a Rule 17(c) subpoena to the government, but that because Rule 16 obligates the government to disclose certain material to the defendant, the defendant’s subpoenas could not exceed the scope of Rule 16.45 Further, the Court held that the subpoenas could only require production of material if the party believed in good faith that the material would be used as evidence.46
In Nixon, the Supreme Court applied Bowman Dairy to a Rule 17(c) subpoena issued by the government to the President of the United States. The Court avoided determining whether “the evidentiary requirement of Bowman Dairy ... applies] in its full vigor when the subpoena duces tecum is issued to third parties rather than to government prosecutors,” finding simply that even should the full evidentiary requirement apply, the subpoena was still proper.47
As one court noted, “[t]he notion that because Rule 16 provides for discovery, Rule 17(c) has no role in the discovery of documents can, of course, only apply to documents in the government’s hands; accordingly, Rule 17(c) may well be a proper device for discovering documents in the hands of third parties.”48 Because Rule 16 only addresses discovery between the parties, if defendants seek documents from non-parties, it must be pursuant to some other rule. If this were not the case, the government could prevent defendants from obtaining material by choosing not to obtain it for itself.49 This perverse result cannot be intended by the Federal Rules of Criminal Procedure.
IY. DISCUSSION
A. Propriety of the Subpoena
The government provided Tucker with transcripts of certain calls made by one coop*66erating witness. Tucker has represented that these transcripts indicate that the witness may have received inducements that are not disclosed in his cooperation agreement. Tucker presumably aims to use evidence of such inducements to suggest to the jury that the witness is giving false testimony.
Rule 17(c) states only that a court may quash a subpoena “if compliance would be unreasonable or oppressive.” The judicial gloss that the material sought must be relevant, admissible, and specific applies where the government issues a subpoena or where a defendant issues a subpoena to the government. Nixon makes clear that this standard also applies where the government subpoenas a non-party.50 But the standard is inappropriate where production is requested by (A) a criminal defendant; (B) on the eve of trial; (C) from a non-party; (D) where the defendant has an articulable suspicion that the documents may be material to his defense. A defendant in such a situation need only show that the request is (1) reasonable, construed as “material to the defense,” and (2) not unduly oppressive for the producing party to respond.51
Under this standard, a subpoena of all telephone recordings made by cooperating witnesses while in custody would not always be appropriate because a defendant may not have articulable suspicion that the recordings would be material to the defense. In Nixon, the Supreme Court warned that a Rule 17(c) subpoena is not to be used for a “fishing expedition.”52 Although I conclude that the standard annunciated in Nixon should not apply in the instant situation, the less-stringent standard I apply requires, as a threshold matter, the element of materiality. Under this standard, Rule 17(c) subpoenas are not to be used as broad discovery devices, but must be reasonably targeted to ensure the production of material evidence.
Applying this standard, I decline to quash Tucker’s subpoena. Tucker has shown that the recordings may be material to his defense, and that production would not be unreasonably onerous to the Bureau of Prisons.
Tucker’s position is bolstered by the status of the proceedings. Were his request made six months before trial, the government’s argument that it would be a “fishing expedition” would be much stronger. But Tucker asked this Court to issue the subpoena one business day before trial was scheduled to begin. There is no doubt that Tucker intends to use information gleaned from these recordings solely to impeach the cooperators. Impeachment of the eooperators is clearly material to Tucker’s defense.
B. Scope
Tucker has not demonstrated that all of the Recordings are material to his defense. Tucker is seeking proof that the cooperating witnesses have been offered certain inducements by the government in exchange for their testimony. Therefore, it is extremely unlikely that relevant material would be discovered on recordings created before the initial contact between the witnesses and the government. The government is thus directed to provide Tucker and the Bureau of Prisons with the dates on which the witnesses or their attorneys first spoke with any agent of the government. The Bureau of Prisons shall produce all Recordings53 for each witness that were made on or after the relevant date54
*67The Constitution guarantees criminal defendants the right to confront their accusers, and “the right to cross-examination has been held to be an essential purpose of the Confrontation Clause.”55 This right is meaningless if a defendant is denied the reasonable opportunity to obtain material evidence that could be crucial to that cross-examination. Where a criminal defendant has reasonable cause to believe that a cooperating witness may have been improperly induced to give inculpatory testimony, the defendant should be permitted to gather potentially material evidence.56
Y. CONCLUSION
For the reasons stated above, the government’s motion to quash the subpoena is denied. The Court hereby modifies the subpoena in accordance with this Opinion. Defense counsel and defense investigators are ordered to keep the Recordings and any material gleaned from the Recordings confidential to the extent that the material is not relevant to the defense or the material contains addresses, identifying information, financial information, or other similarly sensitive material. Defense counsel and investigators are further instructed not to share with the defendant or any other party any information from the Recordings that could jeopardize the safety of the witnesses, and to return the Recordings to the government immediately after trial.
SO ORDERED.
. The motion was denied in an oral ruling from the bench on January 25, 2008. The parties were informed that a written opinion would follow.
. This Opinion assumes familiarity with the facts of the case. Only facts relevant to this issue are summarized here.
. It is not immediately clear that the government has standing to object to Tucker’s subpoena (which is directed toward the Bureau of Prisons). A party generally lacks standing to challenge a subpoena issued to a non-party absent a claim of privilege or a proprietary interest in the subpoenaed matter. See United States v. Reyes, 162 F.R.D. 468, 470 (S.D.N.Y.1995) (citing Langford v.

By 1966, three years after Brady, the Advisory Committee observed that ”[t]he extent to which pretrial discovery should be permitted in criminal cases is a complex and controversial issue,” and expanded the scope of criminal discovery. The 1974 amendment “revised [the Rule] to give greater discovery to both the prosecution and the defense,” Rule 16 1974 Advisory Committee Note. Less than one year later, the Committee expanded defendants’ ability to obtain the government’s witness list, noting, ”[t]he Committee believes that it is desirable to promote greater pretrial discovery.” Rule 16 1975 Advisory Committee Note.

. Although I am aware of no reported decisions in this circuit permitting such discovery, there is anecdotal evidence that many courts have done so. See Edward A. Tomlinson, Use of the Freedom of Information Act for Discovery Purposes, 43 Md. L.Rev. 119, 148 (1984) ("Despite the courts' general endorsement of Iozia, practitioners report that substantial document discovery may be obtained under Rule 17(c) if the defendant demonstrates real need”); Tarlow, RICO Report, at 55 (stating that defendants were able to obtain telephonic recordings from the Bureau of Prisons in United States v.

. The government asserts that because this material is intended for impeachment, it cannot be discovered prior to the testimony of the witnesses. See 1/25/08 Letter from Lauren M. Ouziel & Alexander J. Willscher, Assistant United States Attorneys, at 4. Given the significant quantity of recordings and the government’s promise that these witnesses will testify, requiring Tucker to wait until their testimony is complete to begin reviewing the recordings would result in an unreasonable trial delay. See United States v. LaRouche Campaign, 841 F.2d 1176, 1180 (1st Cir. 1988) (”[T]he admissibility prong of Rule 17(c) cannot be fully assessed until the corresponding witness testifies at trial. Observation of this general rule, however, is left to the sound discretion of the district court.") (citations omitted).
