Tony, I was curious about that blend knob. I'll be looking forward to your report on how well it works allowing you to play both guitar and organ at the same time. With the GR-33, I find that I can hit a chord that will fill out the organ sound, then add little arpeggio type flourishes that are heard in the guitar signal but still sound like the chord on the organ side, if that makes any sense.
Bill, tgo
