I just ordered an A/B switch from www.loop-master.com . Looks like great products built like military components. I prefer to run my signal through the Normal channel via my effects pedals because I am better at dialing in my tone on that side. However, by doing that, I don't get the use of the Reverb or Vibrato. I would like the option of being able to switch over to that side if a song called for it. Anyone here ever rigged up their DRRI or other amp that way? Anybody else have good luck with Loop-Master? Thanks.
