TMS! Stands for ""Too many switches!"", and it's pretty obvious that there are indeed a lot of switches in this one. It's not really a secret but most overdrives have very similar circuit designs, mostly varying the type of clipping used.
With the TMS! you can explore a lot of those options. You can set hard and soft slipping with silicon or germanium diodes or with LEDs. you can use an internal voltage doubler for increased headroom, or set two levels of distortion and you can even bypass the input or output buffers.And there's also a separate Bass control.
We also offer custom finishes for all our pedals at no extra costs. Let us know you want your logo on your pedal and we make it happen.
