I have an older Morley PDW (distortion, wah, volume) pedal. The wah and volume functions work OK. However, the distortion just gives a hiss and little, if any, noticeable distortion. Morley say this should work and suggest sending it back to them for a check out. However, I've seen a few posts on the net suggesting that the PDW distortion doesn't do much anyway. Before I potentially waste my and Morley's time sending it back to them, I'd be interested to know if anyone out there is using their PDW distortion OK on their bass. Thanks!
