Independent shopping perspective
The Korena take
Built for pedalboard tuning, the TU-3W combines chromatic tuning with dedicated Guitar/Bass and Guitar Flat modes. Its LED display keeps the tuning readout visible, while the buffered/true-bypass selector lets you choose how the pedal passes signal when it is not tuning. Guitar/Bass mode accommodates six- and seven-string instruments, and Guitar Flat mode addresses drop tunings. The metal enclosure and 100,000-stomp-rated footswitches suit regular floor use.
Strong match
Who this is for
