This Peavey Alpha tube preamp works as it should and sounds very good indeed. Tube warmth and very nice EQ sections give you that sweet bass tone....and at a bargain price. The preamp is in very nice condition with little rack rash. I have installed new Groove Tubes in the unit which uses a pair of 12Ax7A's. It really sounds terrific. Please ask any questions that come to mind. firstname.lastname@example.org The price is $125 shipped. I purchased this at a bargain price and am passing it along to the buyer.
