Got the amp used, and the inside looks like it was an apartment for a cat, and more recently a colony of dust bunnies. the reverb is in a sack covered in dust, and recently when I turn it past 1 it makes a gritty buzzing, as I play, not stand alone. When I wiggle it, it does go SPROING!

I'm going to try cleaning it, but it's rather a light reverb, when some money rolls in, I want to upgrade to a reverb capable of turning any room a pipeline or cathedral. Whats a god fitting tank at a good price?
