This unit needs some TLC. It does turn on and does produce sound - but the sound is quiet and weak. Someone with the skills to repair vintage tube amps will need to look at it. The tremolo works - but the reverb does not. Also, I'm fairly sure that the speakers in the cabinet are not original. I got it that way. Despite all that - it is still a sought after amp and since it comes with the original cabinet and the pedal - I've priced accordingly.
