    i own the vox, and love it, but am wondering if anyone has hand's on experience with both. i did a full tube roll on the vox, but still have the greenback in it. it does very well with both fenders, and gibsons, but there's a prri somewhat close to me that i might be able to score for a decent price. not having one at my local stores to try, i'm just curious if there are any bugaboos about them that i should be aware of.

    no, i'm not expecting it to sound anything like an original, but just checking to see what the general consensus is.

    thanks

    I used to have a Vox AC30CC1 and now I have a 68 Custom Princeton. Still wish I had the Ac30 but it was way to heavy. The 68 Princeton is very dark in comparison to any amp, much less a Vox. I'm thinking of selling mine. If you like chime, go with a 65 PRRI, not the 68. My 2 cents.

    Your Vox can come pretty close to a PRRI on the normal channel. More versatile in my opinion. Although I use my PRRI a lot for studio work, based on size, I would definitely want the Vox AC15C1 for jamming around town.

    well, i went ahead and got the '68 prri. i knew it was darker sounding (and it is), but i'm going to play around with it, before offloading it. i really see no way to get the high frequencies up to normal fender snuff, unless i get an eq pedal..which i really don't want to do.

    this one had a speaker "upgrade" to a naylor 10/40. it definitely has a very tight low end (even on 0), but the low to upper mids are way pronounced on this amp. my teles (which sing like angels through my ac15c1) just don't snap as much through this amp. they do get the benefit of the tight bottom end, but at a cost.

    i'll either go ahead and dive into some kind of modding, or just move it along. i'll give it a couple days before deciding. you guys were all correct, and i heard it before buying. sometimes i'm just a glutton for a challenge. :)

    one thing though...this amp is pretty effing loud. it packs a pretty good wallop from 6 until total compression, and is very spikey even at 5 or so. folks who think they can't gig with this amp must be playing with some seriously loud dudes. :)

    Mine is plenty bright with the stock speaker. I used it at an outdoor fest on 4.5 this weekend. Restrained drummer, but I had to be careful not to be too loud even at 4.5.

    i just recorded this. no added eq, just as it came through the mic, with a slight limiter to tame any transient spikes. the first guitar is my r0 les paul, first clean (all three positions), then with a little dirt from my lovepdeal od11. then i moved onto my '59 tele build, same scenario.

    the amp volume was only on 2 (which is funny that the end of the lp phase, i was getting feedback). the eq was set at 0 on bass, and 10 on treble, for both. somehow there has to be a solution to the mids growl on this amp.

    i will say it records better than it sounds in the room. the mic (sm57) was pointed right at the center of the cone, trying to milk as much high end as i could. :)

    sorry, it's a long clip, but i wanted to be as thorough as i could (bad playing aside).

    I gig with mine all the time. I've been using a Joyo American Sound pedal to brighten it up. I've also replaced the speaker with a Ragin Cajun.

    Both are great, but I'd rather have the AC15.
    I prefer the darker Vox reverb, and the tighter, more intense drive.

    you are better off getting the 65 PRRI (unless you want to modify the 68) if you play with humbuckers. The 68 is too dark, or rather, has too much woofy bass to work well with HB guitars if a bright BF fender tone is what youre after

    Did you buy second-hand? If that is the sound with treble on 10 and bass on 0, something is not right with your amp.

    Yes, I got it used. The owner swapped out the celestion for the Naylor 10/40. Otherwise, it's stock, and only a few months old.

    From many accounts (here and elsewhere), this is just a darker amp.

    so i went to naylor's web page, and this is how they describe the 1040 speaker.

    The 1040 is a Hot-rodded vintage design. The speaker is a classic Jensen-style cone with a beefed-up magnet and voice coil. This will give you the great snap, chime and transparency of a 10'' speaker with the added benefit of extended lo-end reproduction and power handling.

    • 10'' - 40 watt speaker
    • 1 1/2'' voice coil
    • 30 oz. ceramic magnet
    • Efficiency 98db at 1 watt
    • Available in 8 ohms
    this doesn't sound like a good match for this amp, especially considering it's prolific bass in the tone stack. maybe i'll try throwing in the original celestion, but i doubt i'd end up with that speaker long term anyway.

    i'm probably just going to move this amp along. it has some nice features, but it sounds nothing like any sf princeton i've ever heard. too many mids and no way to eq them out, without resorting to pedals. maybe i'll see if someone wants to swap this for a '65 version, which it sounds like i'd probably like better.

    No to me. But I've retubed the preamp with NOS tubes also. Speaker is fine for the amp.

    I don't know that speaker at all. But I'll reiterate that I don't think your amp is right. The changes from that to a BFPR are minimal. It is slightly more touch-sensitive and maybe has slightly more bass. But it is still a very chimey circuit. It doesn't however, have that piercing, brittle, high-end that I can't seem to dial out of Voxes. So maybe you are just missing the Vox sound.

    just curious. what are the original power tubes that came with his amp? since this is a class a/b amp, maybe a tube swap was done, without a proper bias adjustment.

    having said that, most (there aren't many) videos i see of this amp, the tone is more or less the same as my results.

    i'm not missing the vox tone. i still (and will keep) own the ac15. :) i just wanted a classic fender tone to go with it. this current amp setup ain't getting me there, that's all.

    i see (and hear) good things about the pro junior. maybe i'll sell this one and get one of them. my primary objective is recording, not gigging.

    Normally they come with JJs or relabeled JJs. A/B is not the issue. Is fixed bias and does need a bias check when the power tubes are swapped.

    Pro Jr. is a great tone. But surely not the classic Fender BF tone. For that you'd need a PR or DR . . .

    pulled the tube cover. the power tubes are fender branded groove tubes, as well as the preamp and other 12aXx IMG_20170627_181219~2.jpg tubes. the previous owner did kind of bs me, though, unless this model sat on the floor for a couple years.

    last post, as this is now beating a dead horse, long after it has been turned to glue. swapped the original speaker back in. it is less efficient, but this amp still lacks the fender "sparkle". it just doesn't have it. hell, i plugged in my old '77 sf champ, and it has the sound i'm after, albeit at seriously reduced volume.

    this amp will just have to be moved on. i'm sure there are folks who will love this tone stack, but it just ain't for me.

    i still kick myself for selling a late '70s (mv) pro reverb i had years ago. i fell for the whole "it isn't real" thing, even though the tone was to die for. :)

    thanks for all the suggestions and responses. it's just obvious now that this isn't what my ears wanted. no harm, no foul. i can probably recoup most (if not all) what i paid for it.
