Topic: Fender Twin; reverb VERY volume-sensitive |

Ok, so I have this 65 reissue Fender Twin with a 15.
I love the tone, and love the tube reverb circuit.
But it seems even if I have the reverb set at 1 or 2, it has a beautiful sound if I am playing restrained, but if I open up the volume pedal it sounds like I am playing in the middle of a subway tunnel. I really don't want to have to go back to an outboard reverb because I love the sound of the Fender circuit, but is there anyway to make it less volume sensitive?
The variance does not seem to be dependent with the sharpness of the attack, just the output volume.

Handy with a soldering iron?
I like replacing the 220k to the grid of the recovery tube with a 100k. That makes the reverb a bit more versatile. You can also try an audio taper pot instead of linear for the reverb control.
Aso, if you clip out the cathode bypass cap of the recovery stage you'll get much less reverb
If all of this sounds like Greek, you should ask your friendly local tech

May just be a bad reverb tank. If you can sub a Fender style in there to check that out that might save some grief. Fender used the Accutronics part# AB3C1B.
I finally got a new tank that was defective in the other day (first in about 50 or so that I have purchased lately). It sounded much as you described. |

If the speaker is allowed to 'talk' to the tank you'll get crazy reverb that's output-dependant... make sure that the speaker frame is not touching the tank... the tank needs to be in its bag, with cardboard across the bottom... I've been known to wrap the tank in bubble-wrap, then stuff it back in its bag. You can pull the tank bag from the amp and set it on a pillow on top of the amp... if this doesn't help then you don't have this problem.
