If I were to have a 1 input to 2 output box, and have one output go through my pedal board, and one clean, then both into a 2 inputs->1 Output box, would that work like a 2 Amp system? Retaining the clean bass sound and but adding effected signal to it? Or is there any cheaper way to have both a Clean signal and effected signal than dual amps? Apart from a Loooper w/ blend pot? Thanks, James.
