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 \u003cspan style=\"font-style: italic;\"\u003e(read more below)\u003c\/span\u003e.\u003cbr\u003e \u003cbr\u003e \u003c\/span\u003e\u003cspan color=\"#112244\" face=\"Verdana\" size=\"-1\" style=\"color: #112244; font-family: Verdana;\"\u003eWith 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. \u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-weight: bold; color: #339966;\"\u003eTell Us About the Upgrades!\u003c\/span\u003e\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-weight: bold;\"\u003e1)\u003c\/span\u003e 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. \u003cspan style=\"font-style: italic;\"\u003e(more on the speaker we chose below)\u003c\/span\u003e\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-weight: bold;\"\u003e2)\u003c\/span\u003e 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. \u003cbr\u003e \u003cbr\u003e \u003c\/span\u003e\u003cspan color=\"#112244\" face=\"Verdana\" size=\"-1\" style=\"color: #112244; font-family: Verdana;\"\u003e\u003cspan style=\"font-weight: bold;\"\u003e3)\u003c\/span\u003e 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. \u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-weight: bold;\"\u003e4) \u003c\/span\u003eA \"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 mids a touch, pull back. Warm the tone a bit, turn up. \u003cbr\u003e \u003cbr\u003e \u003c\/span\u003e\u003cspan color=\"#112244\" face=\"Verdana\" size=\"-1\" style=\"color: #112244; font-family: Verdana;\"\u003e\u003cspan style=\"font-weight: bold;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan color=\"#112244\" face=\"Verdana\" size=\"-1\" style=\"color: #112244; font-family: Verdana;\"\u003e\u003cspan style=\"font-weight: bold;\"\u003e5)\u003c\/span\u003e The addition of a Standby Switch.

This also allows you to change out the power tubes to 6L6's for a different tone and response. \u003c\/span\u003e\u003cspan color=\"#112244\" face=\"Verdana\" size=\"-1\" style=\"color: #112244; font-family: Verdana;\"\u003eOverall, we recommend staying with 6V6 tubes, but the 6L6 tubes will deliver slightly more bass, but will be a bit more stiff in response. Stiffness isn't a bad thing if that's what you are going after, but the majority of people will prefer the slightly softer response of the 6V6 tubes. Naturally, your mileage may vary.\u003c\/span\u003e\u003cspan color=\"#112244\" face=\"Verdana\" size=\"-1\" style=\"color: #112244; font-family: Verdana;\"\u003e\u003c\/span\u003e\u003cspan color=\"#112244\" face=\"Verdana\" size=\"-1\" style=\"color: #112244; font-family: Verdana;\"\u003e\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-weight: bold;\"\u003e7)\u003c\/span\u003e External Bias Points have been added so as to more easily bias the amp when you swap out tubes.\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-weight: bold;\"\u003e8)\u003c\/span\u003e Removal of the tremolo circuit.
