| I Recently Purchased a Great Sounding Sho-Bud Amp! The reverb pan is mounted to a strip of plywood, which is mounted to the bottom of the amp! The reverb is very sensative! Should I try putting a piece of Rubber between the 2 plywoods or wrap the unit in something that would shield it better than the present thin tolex sleeve ??Any suggestions will be greatly appreciated! Thanks! Al Udeen |

Al, I had the same thing with my 77 WEBB.......you even looked at that thing cross-eyed & it would develop the most powerful thunderstorm you ever heard! I think just from use & maybe some ABUSE the reverb springs in the pan become stretched out. I tried all the tricks you've mentioned and it didn't help much. I ended up putting in a whole new reverb tank as the one in my amp was an old Hammond/Gibbs original tank, same as used in a Fender Twin. You could check the springs inside for any obvious problems otherwise I suggest an exact replacement from: WWW.ACCUTRONICSREVERB.COM Great to work with...they'll even rebuild your original if that's what you prefer!

My Vibrosonic was real sensitive when I leaned it back too. I turned the tank over and screwed the bag down and that fixed it.

In most cases when a reverb gets noisy (clanking banging,etc) it's usually due to fatigue in the springs and they are sagging slightly and touching. With an older amp, such as the Sho-Bud's that haven't been built for years and with the original reverb tank it is probably suffering from old age and sag..(just like some of us - including me).
The obvious best fix is to replace it. However, I've seen some that have taken a couple turns out of the springs and tightened them up. This will change the reverb delay slightly but probably not enough to be noticed.
One word of caution, replace the tank with one that has the same electrical (impedence) characteristics. |

| I had the same problem with my session 500. I mounted the can upside down and it really did help. |
