DigiTech XTC Chromatic Tuner pedal



As of 10/17/26, this is what I currently have on the XTC. As always, when new, verified information becomes available, this page will be updated accordingly.

The XTC Chromatic Tuner was announced as a new member of DigiTech's X-Series at Winter NAMM 2007. It was designed as a pedalboard tuner for guitar and bass, with a bright LED tuning display and a large note readout aimed at making tuning easier to see on a dark stage or in bright light. Thought to be white by some, the XTC was actually a metallic silver chassis with a textured, carbon-fiber style graphic overlay on the top face.

The XTC has an unusually thin paper trail for a tuner that DigiTech announced at Winter NAMM 2007 and that appeared in retailer listings. Some period coverage predicted a February shipment, while another January report still listed price and availability as to be announced. A later forum post also shows that at least one player believed the tuner was already out, but that post does not document a purchase or firsthand use. I have not found a verified production example or confirmed retail sale. My current working conclusion is that the XTC was canceled before a public release, though the surviving record does not establish exactly when that happened or whether any development samples were built.

That open question is a big part of why this tuner deserves a closer look =)



  • Controls:

    • Blue-In-Tune Display: An ultra-high-visibility central blue LED lights up to indicate when your string is locked in and properly tuned.

    • Visual Breakdown: Includes a 10-segment flat/sharp LED row alongside a clear LCD note display.

    • Tuning Reference: A dedicated TUNING button lets you adjust your calibration reference down to double-flat or up to 443 Hz.


  • List price: Guitar Center listed the XTC at $79.95. UK trade coverage reported £69 and an expected February 2007 ship date. A confirmed final MSRP and actual street price have not been located.


  • Technical info:

    • Power: 9V battery or optional AC adapter. Adapter model and power specifications need further research to verify.

    • Specifications: Chromatic tuner; 1/4-inch input; 1/4-inch THRU and MUTE outputs; metal chassis. Display and tuning features are those described in period product coverage.

    • Component Variations: No confirmed production variations located. The existence of a regular production run remains unverified.


  • Heritage: The XTC was announced as part of DigiTech's X-Series. DigiTech X-Series Pedal Index

  • How players could use it: The XTC's advertised features point to a straightforward, pedalboard-friendly tuner. Since I have not confirmed a production unit or found an owner's manual, the points below describe the intended use suggested by DigiTech's published information, not hands-on testing.

    • Stay in the signal chain: The published connection list includes an input and THRU output, allowing the tuner to be placed inline with the instrument and the rest of the rig.

    • Check the note and tuning direction: The large note display was intended to identify the note being played, while the LED row indicated whether the pitch was flat or sharp.

    • Find the center point: DigiTech promoted its Blue-In-Tune center LED as a clear visual signal when the note reached the tuning target.

    • Use the alternate output carefully: Period specifications also list a MUTE output. The exact switching behavior and intended routing are not confirmed without a manual or verified unit.

    • Set the reference to match the band: The TUNING button was described as adjusting the tuning reference. The period wording about its range is not detailed enough to map every setting with confidence.


  • Suggested starting settings: The XTC was designed as a tuner rather than an effect, so there are no tone controls or sound-shaping settings to dial in.

    • Standard tuning: Use A=440 Hz if that option is available. The published material does not confirm the factory default.

    • Alternate reference: Change the reference only when the band, instrument, or recording requires it. DigiTech's period copy mentions a TUNING button but does not provide a complete setting chart.

    • Silent tuning: If using the MUTE connection, test the routing with the full rig at low volume first. The exact mute operation has not been confirmed from a manual.

    • Bright or dark stage: The XTC was promoted for visibility in both dim stage lighting and bright outdoor conditions. Position it where the display can be seen without changing the signal path.


  • Collector notes and release status:

    • The announcement is documented: DigiTech introduced the XTC at Winter NAMM 2007, and period coverage reproduced its advertised features. Retailer pages show that the product was listed, but those pages do not prove that production units shipped.

    • The release timeline is unclear: MusicRadar reported a February 2007 ship date and a UK price of £69. Sonic State's January 24 report still listed price and availability as TBA. A May 2007 Harmony Central post said the writer understood the tuner was out, but the same writer asked whether anyone had tried one and said the local shop did not have it. This is a contemporary claim, not a confirmed sale.

    • Current research status: I have not located a verified production pedal, confirmed retail sale, original box, or owner's manual. That absence supports the view that the XTC may have been canceled before public release, but it cannot prove that no development sample or other one-off object was ever made.

    • The 2015 eBay sighting: Effects Database preserves a reference to one XTC listing seen on eBay in early 2015. The surviving listing reference does not establish what the item was. Two possibilities worth considering are a listing mix-up with the HardWire HT-2, or a nonfunctional prototype or display shell. The record does not confirm either explanation, and it does not establish that the listed item was a working production pedal.

    • Was the XTC related to the HardWire HT-2? The HT-2 later offered a tuner with a note display and a tuning LED array with Normal and Strobe modes; its owner's manual also documents true hardwire bypass. The XTC's period specifications describe an LCD note display, LED row, and THRU/MUTE outputs. Those broad similarities and differences do not establish a design relationship. I have found no development documents showing that XTC circuitry or software was reused in the HT-2, that the HT-2 was built entirely from scratch, or that a bypass-design change explains the XTC's disappearance. The XTC's own bypass design has not been verified.

    • The most careful description for now is: announced and marketed in 2007, but apparently never released to the public; production and the fate of any development samples remain unconfirmed.

    • The period imagery shows a metallic silver chassis with a textured, carbon-fiber style graphic overlay. Any cleaner or alternate-color render should be treated as an illustration, not a surviving production photograph.


  • Known quirks and tips:

    • The phrase "double flat to 443 Hz" appears in period feature lists, but it does not explain the exact reference steps or how they are displayed.

    • Published material does not provide tuning accuracy in cents, calibration range, display response behavior, or a detailed operating procedure.

    • No verified owner's manual, circuitboard photograph, production serial range, or confirmed production-unit example has been identified in the sources reviewed so far.

    • Claims that the XTC had buffered bypass, used a particular DSP platform, or could not be adapted to the HardWire line have not been established by the published material located so far.

    • The HT-2's true hardwire bypass is documented, but that fact alone does not explain the XTC's cancellation or prove that its design was abandoned rather than reused.

    • For collectors, preserve the difference between a NAMM announcement, a retailer product page, and a confirmed physical pedal. Each is useful evidence, but they do not establish the same thing.
