Right now I use a Boss tuner connected to the tuner out of my volume pedal. I'm thinking of losing the volume pedal and wanted to get a Peterson Strobe-o-stomp since it's true bypass. But after researching the Peterson, it seems that it is not a chromatic tuner, which I need since I play slide in open tunings. So, does anyone know if the Peterson can function as a chromatic tuner or does anyone know of a true-bypass chromatic tuner? Thanks.
