I did a long and careful side by side today at Guitar Center with three re-issue Fenders, the Princeton 65 Blackface LTD in red wine with a 12" Jensen and 15 watts (35 lbs), the Princeton Custom '68 with its stock 10" Celestion and 15 watts (34 lbs) , and the Pro Jr. IV tweed with its stock 10" Jensen and 15 watts (15 lbs)... I highly recommend you do the same! Do not go by reputation.
The '65 was a distant 3rd place for jazz, it couldn't keep up with the push of my playing dynamics through its 12" speaker , the tone was sort of thin and sounded as if too many "mids" were missing. I had the store staff assure me it was operating normally. The Pro Jr. was the warmest, nice clear and present mids, but the '68 was bigger sounding with a classic silverface Fender Reverb-ish. Think Twin silverface. The '68 and the Pro Jr. both had better push in terms of translating dynamics through their speaker behavior. They had "push". I used my P90 pickup Epi Casino guitar. I had another guitarist with me and he came to the same exact conclusions.
I have owned blackface Fender amps: a 60's Super Reverb, a 60's Deluxe Reverb, and actual 1968 silverface Princeton Reverb and a blackface 60's Vibrolux Reverb. I have used and heard many vintage silverface Twin Reverbs.
I've been around, here was my rig in 1970: https://www.jazzguitar.be/forum/attachme...rry_lespaul-jpg
