FDP Forum / Fender Amps: 1985 - Current / '63 Vibroverb RI - Questions for owners (or ex owners)



Jan 25th, 2012 10:37 AM   Edit   Profile   Print Topic   Search Topic

Hi, I was wondering how quiet or noisy this amp is, here's why.

I currently have a "Custom" Vibrolux Reverb which has the exact same transformers and circuit board as the '63 VVRI. It has a couple differences in the circuit mainly the absence of negative feedback, making the CVR really noisy. It is very popular among CVR owners to revert the circuit to VVRI specs, commonly called the "Moyer Mod".

In my case I have done the changes, actually I put a switch to add/remove the negative FB. The amp is about half as noisy as it was but still has a decent background noise. At least more that my original silverfaced amps.

So is you '63 VVRI dead quiet when you flip the standby switch, even with no guitar connected or does it hum ?

My '63 VVRI is very quiet, even while using an OD pedal.

Don't really find my Moyer-modded CVR to be noisy at all. My SuperSonic (original version) otoh...

My '63 Vibroverb reissue is extremely quiet; no hum, no hiss.

Mine was also dead quiet. One of Fender's best amps in the last 20 or so years, imo.

My 63 VVRi is also super quiet.

Have you popped different tubes in? I have read a few places that folks had noise with the stock GT's.

My Moyer Modded CVR is very quiet. I'd look into the tubes you are using and try to get NOS preamp tubes if possible. I find NOS RCA 12AT7's are great for the reverb. Tung Sol Reissue 12AX7's also sound good in the amp.
