I'll be using it in the loop for sure. It will probably sound pretty terrible if I put it in front of the amp with my usual high gain settings.You going to use the delay in the FX loop or out front? I've had a few issues with my carbon copy in the loop of one of my amps. It works fine in other loops though.
Boss DD-7 seems to be a winner in most FX loops. I really like the minifooger delay for a simple analog delay too. Seems to work well in the loops I've tried it in.
