Full Description
Tiny Tuning

Tuning is essential to any guitar and bass pedal board. When you’re short on space, it can be heartbreaking to have to place a tuner in the place of one of your favourite overdrive or delay pedals. Pedaltrain’s SST Chromatic Tuner is the tiniest tuning pedal board utility available, solving this problem. Fitting snugly between the other pedals on your board, the SST – which stands for Space Saving Tuner – offers high accuracy tuning. Just plug it into your signal chain, power it up, and get tuning. SST makes tuning easier than ever.
