This is a great sounding (re-tubed) amp from 1974. It has tons of head room and a great, glassy, jagged distortion in the brilliant input. I don't miss the lower sustain because the sound has so much unique character. Plus, a dyna comp remedies that pronto. It is also great as a clean amp if you put your processed sound into the normal input if that's your thing.
Nothing bad to say...unless you have to lift it yourself.
