Seller's description

The Vintage Sound Jazz 20 is a custom 1x12 combo amplifier that caters specifically to the Jazz guitarist. It's essentially an all hand-wired, all USA made, super-modified Fender Princeton Reverb with the tremolo removed and custom voiced for Jazz. It's based on the "blackface" Fender Princeton Reverb (AA1164) used from 1964-1967, but with several major and significant upgrades (read more below). With it's beefier output transformer, the Jazz 20 has a considerable amount of warm, clean headroom, and noticeably more than a typical blackface Princeton Reverb. Tell Us About the Upgrades! 1) The most obvious difference is the 12" speaker upgrade. The Princeton Reverb came with a 10" stock speaker, and many people modded them to replace the 10" baffle with a 12" so they could get a standard sized speaker in there. (more on the speaker we chose below) 2) Custom tonestack voicing. Rick Hayes at Vintage Sound has worked for many years with jazz guitarists all over the country refining the voicing for his Jazz series amps. 3) The reverb circuit is vastly upgraded. The stock reverb on a Princeton was a small 9" pan spring reverb. The Jazz 20 uses a large 17" spring reverb pan that's the same size as the one used in the Twin Reverb! The reverb circuit also includes a very nifty reverb dwell control for varying the decay time giving you more control over the reverb effect. 4) A "MIDDLE" tone control has been added that Princeton Reverb amps didn't have. This addition does nothing to hurt the integrity of the circuit or tone. The original Fender circuit actually had a "fixed mid" that was set permanently at 6.8k. Vintage Sound removed this resistor from the circuit and replaced it with a much more versatile 10k pot. You now have the ability to adjust this frequency range without compromising the original tone. If you want it to sound precisely like a blackface Princeton Reverb, just turn the port to around one o'clock on the dial and you're there. You want to scoop the mid
