I went to use my TS9 today and it's not working. Here's what it does: - Will not pass the signal unless it's plugged into power - When turned on, the gain knob does nothing - When turned on, there is a lot of volume boost This pedal is only a couple of years old and only used at home. It worked fine a month or so ago, and has been sitting on the floor by my amp ever since. I'm hoping for an easy fix if anyone has ran into this before. I am handy with a soldering iron.
