I am posting this great preamp inspired by Sunn/Beta. I acquired this unit in trade with another great TB'er. He stated that he had this unit completely redone and soldered by Addison Eilers. There is a lot of history with this company, and this could very well be the only functional unit out there. I have the original power cord and channel switch pedal. All in excellent condition. Full 3 band EQ, Gain, and Level on each channel. The EQ on each channel is independent, but the gains are complementary to one another. A master volume tames the beast. An effects loop is available for each channel. Channels may be run individually or in combination for maximum destruction. This thing can get incredibly loud. It reminds me of a rack mount Rusty Box. This is a 2u sized unit. This unit can go from nice and punchy with a lot of native midrange presence to full blown Sun o))) tones at the turn of the gain dial. I've never heard something this heavy. It is just a little too much for me and deserves a good home with someone who will let her sing loud. More pictures can be taken upon request. I just have to pull her out of the rack. The asking price is $500 shipped in CONUS via Paypal. International shipping can be negotiated. Thanks for looking!
