T2 Chromatic Tuner

T2 Chromatic Tuner, from the late 1990s

The T2 Chromatic Tuner was announced at the Winter 1997 NAMM meeting, at about the same time production of DOD's FX12 Tuna pedal tuner began. Likely based on the FX12's circuit, but adding a Recalibration feature, the T2 was probably intended to fill a gap in DOD's lineup for a small, low-cost tuner. However, with only three fine-tune LEDs (flat, sharp, and in tune), with no way of knowing howflat or sharp you were, using the T2 was probably less straightforward than other quartz tuners of the day with needle indicators. In addition, the T2's accuracy (e.g., +/- 3 cents?) was apparently never published, so it is difficult to compare it to other tuners. The T2 was not given a serial number sticker, and it is unclear how long it was produced. However, it appears that the T2 was discontinued by 1999.

• Displays: Note Indicator, Flat Indicator, and three fine-tune LEDs (Sharp, In Tune, Flat); Control: Calibration button (for tuning to a note other than A = 440 Hz)
  
  
• From the DOD T2 Chromatic Tuner Owner's Guide (see link below): "The T2 is ideal to use for tuning Electric, Acoustic, and Bass guitars. The T2 offers precision quartz tuning with an easy to read display. The T2 also features a built-in microphone for tuning of acoustic instruments and a re-calibration mode for quick tuning reference changes."
  
  
• Made in the USA? Although the T2 was introduced a few years before DOD shifted production to China, its country of manufacture is not known. Like the FX12 Tuna, the T2's box does not indicate where it was made, but unlike the FX12 the T2's manual does not mention anything either. The tuner itself does not have a serial number sticker or any other markings.
