Sounds clear and punchy even at low volumes. One thing I am noticing is that I really do have to play with …

    sounds awesome. good bottom. However - I know it's used and I bought it as is, but there seems to be a short on the on/off switch. I have to hold my mouth just right to keep it turned on. I am concerned that it will crap out on me right in the middle of a gig.

    I've been thrilled with the tone and punch I'm getting out of this rig.

    If you're going to go Solid State then this is a hell of an amp. I've got an SVT Classic as well and yeah, you can tell there's no tubes in this thing but for solid state, what incredible control and excellent tone. The compressor though it only has one knob is incredibly useful. Strongly recommend.

  • GREAT AMP!

    Kendra if your amp was clipping (Fault light) you had the Gain set too high, and the Master volume wasn't high enough, you were overdriving the preamp and it is shutting itself off to avoid damage. Read the instruction manual, and learn how to adjust your Gain & Master volume levels. It isn't a "Common Problem" except with those that don't know how to adjust the levels.
