While you are talking about the Zoom G1, I am looking at purchasing either a Zoom G1 or Digitech RP55. The Zoom is a little cheaper and has more drum sounds than the Digitech. My main question is that I am looking at them acting as preamps so connecting my electric directly into a mixing board and avoiding using an amp. The Digitech manual goes out of its way to mention Cabinet Modeling but the Zoom doesn't. Will both work connecting directly to a mixer and not using an amp?
