! Vintage Gallien Krueger MB 150 Microbass Amplifier. Late 80\'s/ Early 90\'s model. The best little workhorse amp I\'ve ever owned. The speaker needs to be re coned. It is not blown but makes a flapping, vibrating sound. I tried to capture it in a pic (missing part of the ring of speaker). Recone kits can be purchased anywhere from 25-60 dollars. The only reason I never reconed was because I played it through an external speaker, and it sounds better like that. Anyone familiar with these little amps know how they sound. I played small bars with this amp ONLY for years and never got close to full volume, even without an external speaker. The amp is in excellent condition otherwise. Classic GK sound with killer compression. A few scratches here and there, and the speaker MUST be reconed to function properly. But with an external speaker, she\'s good to go now. Approx. measurements are 13.75\"W x 15\"H x 7.5D. 12 inch speaker. Please contact with any questions. Payment via PayPal due within 2 days after sale close, and I only ship to the US. Thanks for looking!
