oh i am talking about series
guitar -> channel 1 input. output from channel 1 pc102 -> x value resistor (this was being tested on) -> channel 2 input on pc102
switchable, of course
i figure if the amp is worth little on the resale market due to undoing previous "repairs" by any means necessary (voltage regulator, etc), i might as well make the amp into what will be useful to me
so an in-amp higher gain option and a buffered fx loop (instead of a monitor out) are on the table
