I just ordered an Ibanez Weeping Demon wah pedal from muscisansfriend.com, and after reading through the reviews I came across something that alarmed me, The reviewer said that his pedal worked great until he bought his new Line 6 and the pedal wouldnt work with that amp. I have a Line 6 Spider II 112 and I wonder if wah pedals dont work with certain types of amps, or if its just the case with him.
