This particular guitar loop pedal is the Boss RC-30. Simply put, a loop pedal is a device used to capture sound clips which are then played over and over again (looped) and often overdubbed. While loop machines have been around for quite a while, the idea of a guitar loop pedal is relatively recent. Instead of the traditional box controlled by the hands of a DJ, loop pedals allow guitarists to control the looping and overdub features via foot switches.
âI have a 10 year old Marshall tube amp with an effects loop. I want to use my multi-effects processor with it, but it seems like it kills the sound of the amp when I hook it up. Doesnât matter if I plug in between the guitar and amp or use the effects loop.lug your guitar into the input of the multi-effects unit. Plug the mono out of the multi-effects unit into your ampâs effect loop return. Plug the send of the effects box into the input of the amp (where youâd normally connect your guitar).
