I just ordered a 4 button Voodoo Man switch. There are three colors... red, white, and blue. I saw somewhere the red goes to lead, blue R2, and white reverb/EQ. I tried just about every scheme and so far not getting anything...The only thing working is the reverb light. The other lights have not powered on. About the only thing I am getting is extremely low volumes. I see a white sticker on my amp which says reverb (the return and send knobs are above this white sticker). I also have a yellow sticker which says rhythm 2 (under the direct knob). There is also the "footswitch" input right next to the guitar input. Any ideas?
