I picked this head up used at guitar center. It sounds alright, but has seen better days.
It's been modified, but I'm not sure why. There's a 12-way knob on the back which doesn't do anything, a 2-way switch added to the front which decides whether or not the dist/reverb channel works, and an extra input jack above the footswitch input.
If anyone knows about this amp, please chime in. Are these popular mods? What purpose do they serve when done properly?
I'm also looking for a schematic so i can wire it back to it's original state.
