How to Run Two Guitar Amps With an Effects Loop
- 1). Plug an instrument cable into the guitar and plug the other end of the cable into the main input of the guitar amplifier.
- 2). Run a second instrument cable from the effects loops send on Amp A to the main input on the second amp, or Amp B.
- 3). Plug another instrument cable from the effects send on Amp B to the input of the first effects pedal in the effects pedal chain.
- 4). Plug the short instrument cable into the output of the last effects pedal and into the input of the splitter box.
- 5). Run the last two cables from the outputs of the splitter box into the return jacks on Amps A and B. Alternately, if you have an effects pedal that has a stereo send, you can forgo the splitter box and plug the outputs from the stereo effects send to the return jacks on Amp A and B.
