FDP Forum / Fender Amps: Vintage (before 1985) / 1963 Princeton, would like to brighten up the tone



Apr 22nd, 2019 12:03 PM   Edit   Profile  

I picked up a 63, brown Princeton. It sounds good, but is a bit dark and I'd like to brighten up the tone. It came with the original Oxford speaker. I've tried a Jupiter 10sc, older Eminence alnico and currently have a Celestion goldback in the cabinet. I can brighten the tone with an EQ pedal or boost pedal, but would like to get a brighter tone naturally from the amp. Any suggestions on speakers? I've got a wide variety of vintage tubes to try as well. I've got a brown Deluxe with a Celestion Blue that sounds awesome, so I thought the Celestion gold would have a similar effect on the Princeton.
thanx to all

That amp should have lots of brightness on tap.

When was the amp last serviced?

If you've ruled out old, tired tubes as the culprit, the next thing to check is drifted specs in the filter caps and coupling caps.

About as ordinary as you can get.

I don't have a really old Princeton but I do own 3 SFPR. All are plenty bright plus they are unmodded.
I agree with PeeGoo.

I had two Brown Princetons pass over my bench several years ago. I picked them up for a friend and recapped one while leaving the other stock.

They were both relatively dark-sounding amps, as I recall. Certainly darker than a SF.

Honestly, if you haven’t got there with a speaker swap, yet, I don’t know that you will.

Change the phase inverter input cap from the stock .02 to a .005
