Hey guys, I have a Fusion 550 that didn't come with the footswitch. GK wants $80 for the RFC-II which is astronomical for a damn footswitch. I can find a used one cheaper than that but cost isn't really the thing I am that worried about. I don't need or want the mute function. What I'd really like to do is to have just a single button that would only change the channel to not take up so much space on my board that has an LED. I can mute the rig from my wireless or my GT-5 so a third way (plus the amp face switch makes 4) to mute the amp seems dumb. I could build one, but that thing must be wired all kinds of screwy cause here is what I ran into with various amp switches. Crate single button switch Has LED. No effect. Doesn't work either function. Would be perfect otherwise although it could be smaller. Crate dual button for testing. Mutes and lights the LED. Channel switch doesn't light or work the function. Too big as well. Vox dual button. Changes the channel, (no led...just for testing), but won't mute the amp. Peavey. Normal function. No LEDs and HUGE!!! I did swap in my buddy's Traynor amp one which works fine and has LEDs, but it's more expensive than the GK one and also two button and HUGE. How about loopi brand pedals? They're really small. Anybody got a schematic for that pedal? How can I wire it sans the mute switch? I'm totally into building one. Definitely want an LED.
