If you want that sound get a tweed deluxe or Gibson equivalent (like the ga14 or ga6).That said, her edge-of-breakup tones are to die for and the clean sound is pure 1960s Americana. The dimed small amp thing is not her forte because she is not built or voiced like a small, student amp. As you get her past a semi-dirty tone she exhibits the boxy and ill-defined power-amp saturation that most blackface amps have. I do not recommend turning this amp way up into distortion. Ask Mike Campbell of Tom Petty's Heartbreakers. Unless you are a die hard Fender surfy reverb fanatic (and don't have scratch for a Fender outboard reverb), get a non-reverb. Being older and wiser I now know that the non-reverb models sound better. In the blackface line I feel there are no amps sweeter than the princetons. Being a bassist he didn't want to keep it, so he upgraded the speaker and gave it to my dad who promptly sold it to my uncle. The story goes that this cat who installed the JBL had done some tech work for Blood Sweat & Tears and wasn't paid, so he swiped this from the guitrarist in payment. Stock it had an oxford, so I was happy to have the JBL. Mine had an alnico JBL speaker installed by the guy who sold it to my family (who I know personally, what a crazy, awesome dude). A guy I was in a rock band with collects all different princetons from brownface to silverface chasing my old sound. I pretty much ran her right at the edge of overdrive in all scenarios with both tone controls around 5 and then added drive and level with a conservatively set tubescreamer (at 1st a TS5, later a TS9). I particularly liked it paired with a Guild SF1 or my Carvin sh225. I paid my dues, jazz, rock and blues on this little demon. This was my only amp from '92 to around '99 and remained my go-to until '02. This amp is almost a single channel deluxe reverb, but the difference in the style of tremolo phase inverter and plate voltage on the 6V6es give this fender a softer, touch sensitive sound and feel that's closer to the brownface amps preceeding it. I have seen many 60s Princetons and they always have a GZ34, whereas the silverface ones have 5U4s. The tube chart calls for a 5U4 rectifier (which is way overspec for a 15 watter, Leo was the man), but mine had the stock RCA rectifier, the robust and manly GZ34 (that can easily power a 40 watt amp with only a hint of tasteful sag). The amp runs 2 6V6 tubes in fixed bias for a respectable 15 watts of clean tone through a 10' speaker (the PI structure probably cuts the wattage a bit, but its part of the sound) and she is tube rectified. The preamp is classic blackface 2 band EQ like channel 1 on a bandmaster head feeding a cathodyne phase inverter instead of a long-tailed pair that keeps the preamp tube count down to 3 12ax7es (2 stages for preamplification, 1 stage trem oscillator for the swampy bias-vary tremolo, 1 stage phase inverter, and 2 stages for reverb drive and recovery).

The back features a courtesy outlet for another amp or whatever (but its non-polarized with no ground pin) and an external speaker jack to add a 2nd cab for more projection. The 2 effects can be controlled via the classic 2 button footswitch with an RCA jack. Fender Princeton Reverbs feature 1 channel with volume, treble, bass, trem speed, trem intensity and reverb controls. At first I played it with my 1st guitar, an mij squire strat. It was given to me by one of my uncles who is primarily a classical guitarist. While many will claim jensen was the original OEM for a princeton it seems to vary from year to year with OEM ceramic 10' speakers being supplied by Oxford, Utah and later CTS and Eminence.

Fender also varied OEM speakers a lot during the 60s and 70s. These changes defintiely icnreased the noise floor but its debatable whether they influence the sound of the amp. CBS made changes to all of the amps to streamline production. Every other change had to do with the layout of the circuit. The other significant change came during the silverface CBS period when the volume pot was converted to a push-pull gain boost.

Fender played fast and loose with the use of 5AR4 or 5U4 rectifier tubes as evidenced by exampels with originals tube sintact with tube charts that do not match the factoryisntalled rectifier tube! The effect on the response of a 12 watt amp is very subtle at anything less than full volume and the tubes can be interchanged freely if you have both types and a bias adjustment will probably not even be needed.

During its long and storied run the princeton line of amps with 2 band tone controls udnerwent few significant revisions.
