BOSS is adding two new stompbox tuners to their lineup - the TU-3W and the TU-3S.
The BOSS TU-3W is the "Waza Craft" version of their popular TU-3 tuner pedal. Other than offering the option to choose either true or buffered bypass, it doesn't seem to add anything new to the mix.
The BOSS TU-3S is also based on TU-3, but comes as a smaller-sized always-on pedal. It might be of interest for players who use a loop switcher or a volume pedal with a tuner-out jack.
