Fully serviced by Doug of EARSNYC, given the stamp of approval. Released in the early 2000s. The amp has seen some ware, has some scuffs and the original knobs have been replaced. Sounds killer though. Hard to find, great for the value.
"Ampeg J-20 designed on the Fender 6G3 Brownface Deluxe and featuring a hand-wired point-to-point circuit. Clean and loud, perfect for blues, jazz, rock, and country. Fabulous tube tone and deep vibro. A great pedal platform. The Celestion Vintage 30 12” speaker replacement produces a warmer sound with improved mid-range, a tighter bottom end compared to the original Ampeg Alnico speaker. The speaker upgrade is a huge tone improvement while maintaining the amp's portability."
