That amp has a beautiful sound with or without the mid-range adjustment. I do think I like the subtle sound adjustment around the 4 setting. Seems to bring out the full flavor of the amp.

Use an equalizer !!! I have several EQ s , one for every amp I own !! Set amp tone controls at noon, and use an EQ to Taylor the sound !! Simple and affective !! Remember, if your tone sucks, then it's in the mirror not the gear !!!

Thanks for the explanation video. It’s hard to sometimes find videos explaining amp mods for the Princeton and especially nice explanations of options and also a sound demo. I just finished up a Mojotone PR kit and made this mod, but I didn’t feel like it gave me too much to I reverted it back to stock. A mod I like even more is adding a bright switch with a bright cap.

I did the same mod in the exact same spot but I wired it differently. I installed this on a Pro Reverb and when I use it it is very responsive. But the difference I think in how I installed it is that I jumpered the wiper to that open terminal you left unused. I get a significant boost using the pot. I do this on all of my amps because it allows much more sensitivity in the tone stack controls. It also cuts out unnecessary mid-range bleed in Marshall amps giving you more control of how much mid range you want to dial in.

can someone explain to me the point of the aux speaker jack? what is the point of it? in order to run a cab you have to disconnect the internal speaker anyway.

Id be tempted to try a 50k. Vool vid . Thanks

The higher value pot would be better! Taking the tone stack out makes it like a tweed champ! But I also think you can make it sound like a brown face princeton!

FANTASTIC MOD! Gonna try it today!

I did this but used a 4.5k resistor with the pot so at mim I could go more scooped or mid heavy

Thanks for this great video. Is this a linear pot or audio/log pot? Am wondering if I can put a small put where the second input jack is. Or maybe the Reverb footswitch jack. (Who turns off reverb?)

Thanks. More amp videos, please! Are that an audio or linear pot?

I have a 65 Princeton Reverb reissue (which I love) . . . however I can only put the Volume on 2 in my tiny NYC apartment. Is there a device that "Will not Damage my Amp" - and allow me to put the volume on 3.5 or 4? - I'm looking at the Tw Notes Captor X and the Fryette Power Station PS-2 . . .Any input is greatly appreciated.

So its like adding a variable resistor?

how would you go about trying to make it work as an amp with a mid range control would, like you said around 4:30?

can you make this mod to a deluxe reverb RI

I wonder if you have it the wrong way round. The lower the resistance in your pot, the more mids are bleeding to ground and vice versa

Hello. What gauge is the red wire used? thank you
