Peavey MAX preamp Works perfect. Has lots of scratches. Two knobs are missing but you can still turn the posts, or order a couple from Peavey if it bothers you. Recently replaced pre-amp tube Selling because I replaced it with a BBE BMAX pre-amp I bought it from a friend for $150 about 11/2 years ago, and I used it the entire time on many gigs. The DI sounds great at larger gigs, and the crossover works excellent on bi-amp setups (which I dont use anymore, but used to) Great pre-amp at a good price PM / E-mail with questions
