Maybe the best tuning pedal ever. I like it better than the Peterson because there's no scrolling to get to the tuning you want, simply hit one button and you're there
Has pre-set chromatic, guitar and bass tunings, and you can program 3 of your own. Currently has b0b's meantone E9th & C6th, which are pretty darn nice.
