Leave it to the tone-obsessed engineering staff at Ampeg to come up with the no-compromise, 20-watt, all-tube, point-to-point wired J-20 combo. Part of the Diamond Blue Lead Series, the J-20 Jet’s retro-styling is highly evocative of the ’60s in attitude, as well as tone.
J-20’s preamp section boasts not one, but three 12AX7 tubes, and its dual 6V6 output stage operates in fixed-biased mode. The end-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 is a no-compromise guitar combo ideal for even the most tone-obsessed guitarist. Credit: Ampeg.
