I was just thinking about the line out of my pedal board. I thought using always the this preamp in the power amp of the amp that I'll get at gigs (usually the places I play in provide amps). If it won't work with most power amps I think I'll just put it in one box with my power amp-this will make things easier but will make my tone to change because of the amp (I have a 5-10watt chipamp which can take the signal straight from my guitar)
