Description

Boss TU-3 Chromatic Tuner, a pedalboard standard for good reason. It has a large, bright display that stays readable on a dark stage, and it’s fast and accurate for guitar and bass.

It works as a chromatic tuner, with guitar and bass modes and flat tunings. The reference pitch is adjustable, and you can switch between the needle meter and stream display. It has a buffered bypass and a separate bypass output, so you can mute the signal while tuning. A DC out jack lets it power other pedals from the same adapter, which suits a daisy-chained setup.

Condition notes: Fully working. This is a used pedal with visible cosmetic wear: scratches and small paint chips across the enclosure, mostly at the edges and corners, all shown in the photos. The display, footswitch, jacks and controls work as they should, with no cracks or structural damage. Please look at the photos carefully, as they show every side.

Power: Runs on a 9V battery or a 9V DC centre-negative adapter (not included). The battery currently in the pedal is flat, so you’ll need a fresh one or your own power supply.

Included: Pedal only. No power supply or original box.
