The BOSS TU-3W Waza Craft Chromatic Tuner benefits from the legendary TU-3's tuning abilities, as well as the superior standards of the "Waza" tradition, to create the perfect combination of sophisticated style and unbeatable performance.

Outstanding tuning abilities

Guitarists the world over reach for the BOSS TU-3 as their tuner pedal of choice for a number of reasons: pin-point tuning accuracy; easy to read display; portability; and road-ready rugged construction. The TU-3W features a 21-segment LED display that guarantees exceptionally precise tuning accuracy with an easy to read display.

As with the TU-3 there are Chromatic, Guitar, and Bass modes to meet the tuning demands of a wide range of instruments. The Chromatic mode utilises the on-board 21-segment LED's to guarantee 100% accuracy; whilst the Guitar and Bass modes enables support up to six half-steps (semitones) below standard pitch for "drop" tuning - as well as accurately tuning 7-string guitars and 6-string basses without any fuss.

Buffered and True Bypass options

The redesigned circuitry of the TU-3W offers selectable buffered or true-bypass operation. However, elaborate your pedal arrangement is, pristine signal quality is important for every guitarist, and transparent audio pass-through is assured thanks to the design by the peerless Waza Craft team.

Waza Craft Tradition

In Japan, "Waza" is the term for art and technique, and as part of their Waza Craft series, the illustrious team at BOSS perfect their already exceptional pedals, to deliver premium gear at ludicrously affordable prices. By carefully selected analogue components, refining circuitry and executing meticulous attention to detail, we all benefit from their legendary expertise.
