I bought everything separately. I used Classic Tone iron.
It's a real saggy amp, but is more articulate than an amp (Marshall) with a cathode follower driver tone stack for the most part. You can hear the power supply do a catch up for a split second when you do a quick back off on the guitar volume.
You'll need an attenuator if you plan on playing it at any volume lower than a full rock band! This amp gets it's sound from power clip distortion, not a high gain preamp. My clips would sound better if I could play at full volume and get the speaker moving. But whatever.. It's cool to have something different than the standard uber gain buzz box tone.
