Amp Selector

"A/B amp selector without ground loops"



The Amp Selector routing rack effect module gives you A/B/Both amp selections without ground loops.



The Amp Selector module lets you route an audio signal to one or both of two amps.  The amps are isolated by transformers and have Ground Lift switches to prevent noise and ground loops.  See the Amp Selector User Manual for usage details.
