I Finally achieved my long time dream of getting a vintage model t. It's a 74 silver knob. My question is When you put into the input that allows you to run both channel does this make the other inputs output? In other words are they wired in parallel? I have seen some bands run multiple model ts and it looks to me, that they run a jumper cable from normal on channel two to another model t. Or is this some kind of mod? I don't have my amps and cabs near by to test this out. Any help on this would be awesome.
