GoGo’s Caliber Tuner has a calibration mode accessible on its side for setting the tuner to alternate references other than A=440 Hz. You can set it to reference pitches from 430 Hz to 450 Hz but know that whatever “A” frequency you choose, it is indicated right on the display.
I liked the gun metal or metallic silver case of this chromatic tuning pedal, and I found the +/- .5-cent accuracy so exact it showed the wonky behavior of a new set of strings immediately. The Caliber will detect pitches from A0 (27.5 Hz) to C8 (4,186.00 Hz) making it ready to tune bass guitars, synths and well as drop tuned guitars.
The pedal is equipped with true bypass and provides daisy chain power jacks for other pedals and the giant high definition screen makes it is easy to see GoGo’s signature “green you’re in, red you’re out” display. A standout and big winner down on my pedal board.
The GoGo Caliber Pedal Tuner sells for $99 MAP.
