DESCRIPTION: Marcus Jidell playing a C-tuned Gibson SG to show the response! The amp gets a completely new preamp with four channels. Clean, Crude, Crunch and Lead. All channels have their own controls at the back. Gain, Tone, Volume controls for each one. The front master and four tone controls are global. All channels are run through a mini class A amplifier for a pure output tube distortion character. There is also a metal switch for modern style. It affects all channels but mainly Crunch and Lead.
