I am selling a SWR SM500, the amp is in great shape and has been used very gently. it has spend most of its life in my house and has been used for practice and recording, never pushed hard at all. everything works the same as when I bought the thing new. for specs and technical info go here: http://www.swrsound.com/products/proseries/sm500.html I am looking for $525 and that will include shipping to any of the lower 48 US states. if you have any questions let me know.
