Fender Custom Vibrolux Reverb : Reverb driver tube help!

[Soulboogaloo]

Hey guys,

just bought a Fender CVR, and even if it's stock (I mean no "Mark Moyer mods" here for now), I'm very happy with it... except for the reverb, that sounds pretty weak I think...
So I'm considering replacing the 12AT7 by a JJ 12AX7.
Is it possible, without changing anything else, I mean any resistor value or so?

Sorry for the rookie question guys, I'm no tube specialist at all!

Pleease! Somebody could help?

It's usually suggested to stay away from 12AX7's for the reverb tube. I don't know about that amp, but maybe there is a problem with the tank. I'd open it up and see if there are loose springs or a bad connection somewhere. Or try a different 12AT7, maybe the tube is bad (but I doubt it).

Well... it's not a strong reverb. Just turn the knob further up. It won't work like a BF reverb where the entire usable range lies between 3 and 4 on the dial. But, push it to 4, 5, maybe even 6 and see what you think.

I think the 'verb is one of the best features of that amp because it's so much more subtle.
