GP7 SM-150 solid state amp in good working condition. Housed in the OEM plywood rack case. It sounds good! Recently serviced, in good working condition. Not sure of its exact age, but it's pre-Gibson, made in the UK. 150 watts at 8-ohms; 300 watts at 4-ohms. I can honestly say that it sounds louder than these ratings would indicate. 7-band graphic eq plus two pre-shape filters plus sweepable tone control = a TON of eq options, from clean and uncolored to overdriven and gnarly Brit tone. $300 shipped in the conUS.
