I have a Peavey 150 W combo with a 15" Black Widow speaker. It has built in hi/low shelving, graphic, chorus, x-over and many input/output possibilities. I have done a couple of mod's on it: casters for easier transport; binding post connections on the rear to use the amp or cab seperately; I've also had the board checked and resoldered from cold solder joints (happens over time). The board was vastly improved from the mediocre factory job! It's yours for $300.00 Cdn. Email me @ firstname.lastname@example.org Cash or money order only.
