Boss TU-3S Chromatic Tuner

Description

The BOSS TU-3 is the most popular stompbox tuner, trusted by musicians worldwide for its reliable operation and tank-like durability. With a smaller footprint, the TU-3S gives you the same industry-standard performance, saving valuable space on your pedalboard. The display and tuning functions are identical to the TU-3—with only the footswitch removed. Always on and ready to go, the TU-3S is perfect for use in pedal switching systems like the BOSS ES-8 and ES-5, and ideal for any setup where space is at a premium.
