Has anyone tried the Voodoo Lab Amp Swithcer? I think its time for me to get a better AB Box. What I'm doing is switching two four input amps using amp number 1 and amp number 2 at the same time for a clean setting and a dirty setting (one channel of each amp set clean and one dirty) using both cleans together and both dirtys together. Both amps are clean at the same time and when switched both are dirty at the same time ( I like these amps together ). Any suggestions most wanted.
