Greetings, all . I recently bought a Gallien-Krueger 700RB. (Oh, it sounds SOOO killer!) I haven't picked out a cab yet, and I intend to take my time. But meanwhile, would it be safe to run the signal out of the GK effects send...then into the effects return of my Laney combo amp? I would be using the GK as a preamp only, with no load on the power amp (which is solid state). I know all-tube heads blow up if you do this, but I can't seem to find a definitive answer about solid state heads like my GK. Thanks!
