Ok, I've looked through what I thought was most of the threads on the M81 and I never did find a straightforward answer. I even went to Dunlop's website and couldn't find it. So I tried to Google the phrase "will the MXR M81 bass preamp pedal drive a power amp" and got nothing that resembled an answer. I'm asking because I have enough gear left over to put together an "acoustic show/backup rig" so I don't hafta drag out my main rack for my low volume acoustic shows. I have a spare lightweight power amp and a few pedals to put on a board. It would be cool to be able to put a pedal pre on the board, but I need it to drive a Peavey IPR power amp. I know the Tone Hammer will, and I'm ok with getting one, but I like the size and the price of the MXR. So, can the M81 drive a power amp? Thanks. edit: Apparently, I need to clarify that I don't have an M81. If I had an M81, I promise I wouldn't have asked.
