Vintage Jackson Model JG2 50 Watt Tube Guitar Amp Works Great! Made in England This is a rare bird, as only 500 were made. Jackson had just done the Randy Rhoads Guitar, and then contracted Laney to build them a Randy Rhoads Amplifier. After the first batch due to mounting costs they scrapped the project and decided to just stay in the guitar market. This amp sounds like a hot rodded mix of a Marshall JMP and Plexi. The added gain comes from pulling the mid pot out which engages a midboost, and a 3 setting Orange style FAC knob to control how compressed you want the mids. Input one is the high gain channel and input two the clean channel, when plugged into input one you have control over both knobs to blend each channels distortion. When you plug into input two you just have the clean channel and input one knob is disabled. Everything from sparkling cleans to classic rock to classic metal tones. 50 watts powered by 2 El34s.
