The J-20 Jet tube guitar amp is a retro-styled sweetheart of a combo amp highly evocative of the '60s in attitude and tone. Part of Ampeg's Diamond Blue Lead Series, this all-tube amplifier is the product of Ampeg's tone-obsessed engineering staff who came up with the no-compromise design of the 20-watt, point-to-point wired J-20 combo.

The J-20 boasts three 12AX7 preamp section tubes and a dual 6V6 Class AB output stage. The result of all this "inner tubing" is a guitar combo with controllable vintage crunch along with Ampeg's hallmark ease-of-operation. The simple Volume/Tone control setup makes it easy to quickly dial in just the right amount of edge for personal bliss.

With its point-to-point wiring, 5AR4 rectifier tube, 12" alnico speaker, and foot-switchable, bias-vary tremolo circuitry, the Ampeg J-20 amp is a no-compromise guitar combo ideal for even the most tone-obsessed guitarist.
