MOD Reverb Tank Review

I thought I would swap out the original Gibbs tank in my Reverberocket 2 with a MOD. This would save wear and tear on my vintage tank. After installing the new tank today, I was surprised how weak the new tank was. At full reverb, it put out about the same amout as the Gibbs at 2. The resistance through both ends is correct. All hardware inside is in order. I don't know if I can send it back as it is working a little. I was careful to order the correct tank for the Reverberocket (4FB3D1B).
Has anyone else had a problem with weak MOD tanks?

weird

I have had the opposite problem with newer production reverb tanks, usually they are way too wet, with as much reverb at about 3 as an original tank at 7/8.

I'd call the place you got it from and see what they suggest.

Hard to beat the old Gibbs Hammond tanks, and it's also hard to find a good used one for a Fender amp!
I see a lot of old organ reverb tank pulls but the impedance is off for guitar amps.

Did you remove ALL of the foam padding from under the reverb springs
before you tried it?

Yes, the foam was removed and when I pulled the tank back out, I checked to make sure I didn't miss a piece. Today I'm going to hook my signal generator to the input and measure the output, compared to the old tank.

Dumb question since you said you measured the resistance on the connectors, but did you try hooking it up with the leads reversed?

I've noticed that with reverb tanks the input and output labels have seemed to switch back and forth through the years. Some eras the input on the tank seems to go with the input on the amp instead of receive the output from the amp. Maybe that's how your old Gibbs tank was labeled.

I found the problem. I researched the internet to find the right number MOD that matched the Gibbs "C". Five different sources led me to believe that 4FB3D1B was the correct MOD tank. I just now grounded both sides and the reverb came alive. The correct tank was 4FB3A1B.
Ringo was right. This MOD tank is wetter than the old Gibbs.
Thanks for the help everyone. milocj, that is confusing the way the tanks have been labeled over the years. My brain doesn't work so good anyway nowadays; the last thing I need is more confusion.

Good you found the problem. My experience with installing a MOD tank in my Musicman RD112 was just that - nice and wet.

Not to hijack, but slightly related. Does anyone refurb old tanks? I have an old Hammond that had the springs damaged in transit, but otherwise seems ok. Hate it sitting around useless if it could be fixed...

I had a fender (accutronics) tank that had a broken spring after shipping. All signs pointed to getting a new tank. I still have busted one, but it's such a delicate thing to fix and I couldn't find anyone who works on them. Plus, good luck finding someone who will fix it for less than 40 dollars... the price of a new spring tank. Let us know if you do find someone who can fix them.
