Vintage solid state head by Amplified Musical Products. 100W @ 8 ohms - 250W @4 ohms. It's very clean and must have been a homebody for most of it's life. 2 channels w/ led display, switchable effects loop with post and pre eq in's and out's. It also has a limiter w/led display at the gain control. It has a clear warm sound much like early Eden in character. In the minus dept.- the 'Edge" control in ch. 2 is non functioning. I'm not sure what it did when it worked, maybe like a 'loudnees' type thing. Also there is an intermittent fuzzy static that pops in and out sometimes. This is regardless of which channel is being used and is not affected by any of the controls. It reminds me of a similar thing I had with a Walkabout head. Priced accordingly at $150 shipped!
