I know it's been discussed, but what kind of headroom will this give me? Somewhere between an DRRI and TRRI?

I love my Twin, but it's breaking my back.

hi dph!

when you spend the money on a cvr and the mods, you might as well get yourself an sf vibrolux, or a bandmaster reverb.

the latter regularly sells for around $500 in the states...
add another $300 for a combo-cab and a pair of 10"-speakers and you won´t have to bother modding an amp you might still not be happy with...

mh, at least that´s what i did.
i had a cvr i was not happy with and bought a bandmaster reverb ;)

cheers - C.

Why not buy a 63 Vibroverb RI?

Cost me about $5 in parts and an hour of my time to do the Moyer mods on my CVR. My current medium-sized club gigging amp. Plenty of headroom for that purpose.

Also, one of the reasons the VVRI did not sell well and was discontinued quickly (and thus relatively harder to find than CVRs) is because the VVRI speakers were designed to be '63 Oxford clones, thus had the typical "Oxfart" sound. The CVR has Jensen RIs that, while not perfect, are much better than the VVRI speakers (I swapped one of the 10s in my CVR for an Eminence Copperhead, pairs nicely with the Jensen RI).

That being said, at some point I'd like to add a Vibrolux to my collection, one of the few BF/SF models that I don't have.

I was looking for a DRRI, but happened upon a Vibrolux with the Moyer mods for a pretty good price and think I might bite. I would like a little more headroom than the Deluxe has, if possible, and like the idea of owning an amp that weighs 1/3 less than my Twin.

whos buys VL for headroom.

you may want to look into another amo if thats what you want out of it.

even the newer version knock offs sound great right out of the box with nice natural crunch

"whos buys VL for headroom"

I'm not set on any particular amp, although I'm close to closing the deal on this Vibrolux. I do want a nice Fender Blackface tone. My TRRI is perfect, except for the weight. A DRRI might cut it, but I'm hoping that the CVR with the mod gets me there since I can't afford a Carr Rambler.

I have owned two CVRs and sold both. I never bonded with either of them. The second amp was better than the first and could have been improved with the Moyer mods but....They just didn't float my boat. Too flabby too soon. Sharp chops for bluses rhythms where not sharp. It really isn't a BF amp the way I see it.

The CVR with all the Moyer mods is a '63 VVRI with better speakers. I'd be much happier with a 4-10 Bassman RI than the VV if I was looking for clean headroom in a mid-sized club amp. The SRRI too for that matter but then you are back to hauling a boat anchor. I drag my '67 SR around quite alot, I know. If you are just looking for clean and loud and decent try a HRD. Drive channel is poor sounding IMO but the clean channel is kinda good with pedals for OD.

Just my $0.02 US

+1. The Custom Vibrolux is not a blackface amp. Most compare it more to brown Fenders. It carries more mids than the blackface amps. They still have a very nice tone though, depending on what you're looking for.

I brought the Vibrolux home tonight an did a nice side by side with my Twin. I'm not sure how much of the amp's sound can be attributed to the mods, but it doesn't seem at all flabby, and may have enough headroom to be heard in my 8 piece band.

But I still prefer the sound of the Twin. The Twin just sounds huge and churchbell clean. Not to say that the Vibrolux doesn't sound good, but it does seem a little bright and slightly boxier than the heavier Twin.

Either way, I'll hang onto it for a couple months to test how well it does in the mix against the horns and percussion in my current band.

One thing to try is to replace the phase inverter tube. The CVR uses a 12AX7 for the PI. If you replace that with a 12AT7 you'll get a bit more headroom.



Feb 11th, 2012 03:55 PM   Edit   Profile   Print Topic   Search Topic

I agree with ProToneThinLine..12AT7 in the phase inverter.
DPH, you think the mods have already been done? How is the reverb? (the reverb is normally weak on
these when stock.)What kind of speakers didja get in it? Last point: These are loud amps even when left stock. It should cut through in a band situation easily, because of the mids. Have fun!!!!!

Yes, the mods have already been made. The reverb is fantastic and the amp really loves my ZVEX box of rock. There seems to be enough headroom and it really does sound great, albeit not as great as my Twin to these ears.

My Moyer Mod CVR sounds incredible with a good deal of headroom.

My suggestion would be to put in ceramic speakers that will give you more headroom than the stock alnico Jensens. I've got Eminence Rajin Cajuns in mine and it sounds very good. A pair of Weber 50w 10F150's should really also work well or a pair of Eminence Copperheads should also give you some vintage Jensen tones.

I have a 1969 Vibrolux Reverb and a '63 Vibroverb Reissue. They are VERY different amps.

The Vibrolux breaks up earlier, but has a more sterile type of clean at lower volumes (sterile might be too strong of a word). The mid scoop becomes less apparent as you crank the volume and by the time it's on 7 or 8, you really have to turn the bass down or it gets boomy. It's got Weber P10R's (the predecessor to the 10a125-150?). It's an incredible amp that does the blackface thing to a tee! It rocks my socks.

The Vibroverb on the other hand, is tonal nirvana to me. It's got the mids, from the word go, the reverb is luscious... but the bias vary trem is the tipping point! this amp is so touch sensitive at all volumes and just sits beautifully in a mox. But, I play Blues and Rockabilly... its got that thicker sound... Not dirty, but the cleans are more complex. I am running on P10R and one C10R, which I find is a nice mix.

For most regular gigs I do and band practice, I run the VVRI around 3-4 at most. There is very little breakup with single coils, but my Filtertron Gretsch and Humbuckered Les Paul put some hair in the mix. It stays at that level of breakup until you hit 6 on the dial, then you'd pretty much gotten to maximum headroom. The amp is cooking nicely at that point and slightly louder than the Vibrolux. I hit with a Dano Transparent Overdrive for dirt. I don't like TS type pedals with this amp at all!

Does the VVRI sound like a Twin? Not really. it still sounds like a Fender, but not a like a Twin. Does the VR sound like a Twin? Eh, not really... maybe at much lower volumes? Maybe? But I think it has a different character to it. would an audience be able to tell the difference? Doubt they'd care! LOL

The CVR is based on the 6g16 Vibroverb circuit which is a brownface circuit. Fender lowered the headroom from the original circuit and reverb to both channels because that's what they perceived everyone wanted a dirtier amp in the 90's. The 6g16 circuit and it's variants have bias vary trem and heavier mids. Also, a different tone stack with tapped pots. I am not quite sure how to describe the difference these impart... but they are different in behavior to the Blackface tone stack.

Brownface tone is not for everyone. But I like it. It's my favorite of all the Fender sounds. It's cleaner than the tweed circuits, but not as scooped as the blackface circuits. It fits my playing perfectly. Might not be your cup o tea though?

Well dang Axis40! I think you really characterized the whole thing nicely. I agree with BuckeyeBlues also. Get some ceramic speakers (preferably some with a high sensitivity rating), because you're looking for headroom. I am one of the few people that liked the stock P10Rs in this amp, even though I don't run em' in this amp because I was looking for another sound. I use Weber Michigans,(and I am very satisfied), but they will bring you back to the weight of a Twin because of the size of the magnets. There are several speakers(Emi, Jensen,Weber and CTS vintage that sound good in this amp to me. I love the Blackface tone. But I also love everything this amp brings to the table!!!

i love the tone on the CVR but the prob is thats its not BF tone. and its not a VL as we know it.

Fender did a diservice or discredit to the VL name with this thing. yeah i love it and im thinking about one myslef but its def not BF.

IMO for whht you want you can pick up a nice
early 70's SFVR for about $800 and have it BFaced for about $150. unless you can do it yourself it will only cost about $50 for the kit

just my opinion from what I am reading in what you want

If that's the case, I'm moving back to WV. ;-)

Around here it's REALLY hard to find a decent SFVR for much less than $1,200. The secret seems to be out about the SFVR. It's becoming a very popular amp. I picked mine up last year. I got mine for $1,200, but physically it was in rough shape. Electroniclally it had just been re-capped and re-tunes (with NOS), so it sounded great from the start, but it took me about three weeks to get the smell out of it.....

I have one with Fromel mods, which is basically the same with a few more extras.

The amp doesn't really break up at all now. Dial goes all the way to 8 then breaks up. That may be more the speakers than anything else.

It sounds like a Super to me now, only with two ten's.
