Independent shopping perspective

The Korena take

Built around the TU-3 display and tuning functions in a smaller pedalboard format, the TU-3S is a chromatic tuner that stays on rather than using a pedal switch. That layout reserves room for other pedals while keeping tuning visible and available in the chain. It is specified for use with BOSS ES-8 and ES-5 pedal switching systems, and suits pedalboard setups where space is limited.
