My Soul-Bender has suddenly died, and I'm wondering if anyone can give me an idea what might be wrong. With the effect engaged, the power light comes on, but no sound comes out, either dry or effected. With the effect bypassed, the dry signal flows through normally. This tells me that it's not a connection problem, or a power problem, since the light comes on. It does this both when powered by a fresh 9V battery as well as a reverse-polarity AC adapter. Any thoughts as to what might be the problem?
