The Mod Electronics Reverb Tanks are high quality upgrade units. Some of the major differences between the Mod®s and other reverb tanks are that the Transducers are wired directly to their respective RCA jacks as opposed to current production tanks where Transducers are connected by a detachable plug to their respective RCA jacks. This makes the tanks less receptive to any outside interference. The original Hammond Accutronics tanks from the 1960s were also wired directly to their respective RCA jacks. In addition, very close attention has been paid to the spacing and size of the lamination of the Transducers resulting in a more vintage like tone.

I recently put this tank in my 82 peavey backstage and it sounds great. Will it also work in a 83 Peavey Bandit 65 solo series? Thx
Asked by Anonymous on December 30th, 2016.
Hi, by doing a quick internet search it seems that the 4EB2C1B was used in the Peavey Bandit 65. This is a long tank 2 spring reverb. Since they both have the same input and output impedance (EB) this should work.
the input and output impedance are slightly different. Will this still be safe and sound ok? thx!

My Monoprice 15w amp has a 2EB2C1B tank. Since I can't find any tanks with the number "2" in the first position, I am assuming this tank would be compatible with a 1EB2C1B or an 8EB2C1B tank since they are the same length and all the other position numbers/letters are the same, is this correct?

It would most likely be the 1EB2C1B as the 2 most likely indicates the number of springs. If you would like to incorporate a third spring, the 8EB2C1B would be the tank to select.
Oddly enough, the part number is listed as 2EB2C1B on the later Monoprice - Stage Right 15W combos. The 8EB2C1B is a direct swap and works well even though the specs on output? impedance isn't the same as the stock tank. I've had one in my 15w for 7 months at this point without a single problem. My MOD tank sounds great!

This can vary, so there is not a definitive color coding for the wires, but there is no risk of damage to the amp if the wires are hooked up incorrectly. The reverb simply won't sound right. If that is the case, simply reverse them and it should work.

What is the best medium decay reverb tank for the Hot Rod Deville (4x10)? The stock tank is dead and it was very limited when it was alive.
Asked by Anonymous on October 13th, 2016.
A 4EB3C1B is what the Hot Rod Deville ships with stock. This is a two spring reverb tank with a long decay. For a medium decay look for a 4EB2C1B.

Yes, this tank can be used as the most important specs match(input/output impedance,grounding, etc.). The main difference would be that the 8EB2C1B is a shorter tank.

You always want to pay close attention to the Accutronics numbers. For example in the two tanks you are inquiring about the varied numbers may affect performance and compatibility. I would suggest checking out our tech corner article explaining reverb tanks to determine the tank that will best replace the existing unit.

As far as a straight swap this tank is not compatible with your amp. Some people have modded their amps to allow this tank to work in the Monoprice 15. We are not amp techs and can not advise you on these mods.

The Monoprice/Stage Right 15W amp has had two versions so far: one that used a miniature plastic reverb unit and one with a full size tank. This tank should work with the version with a full size tank, but this can not be installed in the version with the mini tank without modification to the amp.

Hi, I'm looking to replace my reverb tank from an old Peavey Backstage from the early 80's. The tank in there right now is made by O.C. Electronics but has now tank code on it other then "Type 247". I was given resistance values of 100 ohms for output and 348 ohms input but I'm not sure how that translates to impedance. I see that someone asking a question above said they put this one in their backstage but I'm just confused on the resistance values. Will 8EB2C1B work with an 80's Peavey Backstage? Thanks for you time.

This is the correct tank for the Fender Frontman 65R, so this is likely the right tank for the 15R as well, but we do not have cross reference materials to verify this. It is likely that the original tank in your amp will provide some clues as to what replacement you need, my suggestion would be to remove the original tank and inspecting it for information.

I bought this to replace the failed USA-made Accutronics tank in my 2007 Blues Junior. Works great. My only complaint is that the hole pattern was just enough off that it took awhile to get all 4 fasteners started.
I was getting static from my Blues Junior III whenever I turned the reverb up above 1 or 2, especially if I was over-driving the tubes. I found a forum where someone said it was likely the tank. I replaced the stock Ruby tank with the MOD and I've had no trouble since.
This really brought out the reverb in my Fender Super 112. Sounds like a new amp.
I replaced the reverb tank in my Fender Blues Jr. III NOS Tweed, a Ruby reverb tank...was never crazy about it. The MOD tank is a big improvement over the Ruby tank.
Works great. Slightly richer sound than the dual spring Accutronics unit that came in my amp. Screw holes even lined up for a clean swap. Still breaking it in, but very pleased with initial impressions!
The reverb tank arrived surprisingly fast to Canada (one week only), since it was shipped from California. The unit itself corresponds to description and works perfectly, providing an improvement compared the original noisy tank in my Fender Princeton 112 Plus guitar amp. Thanks to AmplifiedParts
Very good product, very satisfied, thanks to Amplified parts.
perfect replacement for fender blues jr.
A world of difference! Better, cleaner sound and more control.I can't and imagine a better upgrade for the price.
OMG - bought this to replace a stock Spring Reverb in my Fender Blues Jr and what a HUGE difference. The stock one "maybe" sounded ok up until 3 on the dial, after that it was just rubbish. This one you can crank, sounds wonderful and is at an incredible price ! Thank you Amplified Parts ! ! !
