Gallien-Kruger 212SC Combo Guitar Powerhouse!

I have owned this amp for about 20 years. It is loud, VERY loud! Features: 2 Celestion G-12-80 15-ohm drivers Rear: on/off switch, polarity switch, grounded convenience outlet, extension speaker jack. Front:1/4" TS Inputs- Normal, and -10 db. Front Controls: 2 sections, A & B, each with the following: Volume, Master, Treble, Hi Middle, Lo Middle, Bass, and a gain Boost in/out button. There is a Contour in/out button, & a Reverb pot. There are 1/4" send/return jacks for A, B, and A&B, and a multi-pin jack for a wired foot-pedal style remote to control A/B, Reverb, and Contour.

I added a small muffin fan on the back to keep the output transistors cooled, and after market tilt-back legs on this beast. It is an awesome solid state amp, with plenty of gritty or clean gain, and 150 watts of power- enough to make your brain swell, and your ears bleed.
