Will this sound good in my Twin?
Asked by Anonymous on August 27th, 2015.
The construction of these MOD tanks is designed to sound as close as possible to vintage reverb tanks of the 60's.This tank would serve as a great upgrade to the stock unit in a Fender Twin.
Will this work in a 94 Fender Vibroking
I have just got a used Fender Sidekick 25 Reverb in working order. Unfortunately the reverb tank is missing.
Can anyone tell which if any modern reverb tank would be a suitable replacement?
The Sidekick is a solid state amp approx 1985 vintage.

You will want to determine several factors regarding your reverb circuit such as input/output impedance, mounting orientation,number of springs, etc. I would suggest visiting our tech corner for a full explanation of reverb tanks. I'll include the address below:
Hi, I have a Fender 1968 deluxe reverb,AB763,and I am looking for a nice lush reverb. Would this be the one to use?
Asked by Anonymous on November 19th, 2015.
The MOD series tanks are designed to sound much closer to vintage sounding reverb tanks than other brands and their construction lends itself well to this goal. This will definitely be a great upgrade or replacement and should provide a nice lush reverb for your deluxe.
I need to buy some tanks for the JCM900 and the JCM2000. Which models of the MOD tanks do I need?
Asked by Anonymous on June 26th, 2016.
It appears from doing a quick internet search, the JCM 900 uses a 8DB2C1B, and the JCM 2000 uses a 4BB3C1D. You might want to confirm these numbers by looking at your reverb tanks. Most tanks will have an 8 character number on them.
Would it sound any better than the factory tank on a Fender Blues Deluxe reissue?
Asked by Anonymous on July 19th, 2016.
Most MOD owners feel that these reverb tanks are the most accurate to the original tanks found in vintage Fender amps. In most cases this would be considered an upgrade.
I have a Peavey Valveking 112 and would like to upgrade my reverb. I can hardly hear it.

Hi, from our limited research it appears that you need an 8EB2C1B for your Valveking. I would confirm this by looking at the number on your tank.

What other tank options are there for a '63 reissue fender reverb unit?
Asked by Anonymous on March 16th, 2017.
As long as the second and third character match (AB) you can play around with the other options. The first character will describe the tank size and number of springs. The fourth character represents your decay time and comes in three different types (short, medium, and long). For more information please see our reverb tank article in the tech corner above.
I am looking for a replacement reverb tank for a 1993 Fender Super Amp (op-amp reverb driver). Is the 4AB3C1B an appropriate replacement? Thank you.
Asked by Anonymous on April 4th, 2017.
From our limited research it appears that the 4AB3C1B was the original tank in your amp.
I have a Mesa Boogie Nomad 100 and need to replace the reverb tank. Your site states that the MOD 4AB3C1B unit will work on some Boogies. I was trying to get a type 9 unit thinking that it would give me the best reverb for the channel 1 clean. Can you guide me on that? Thanks. Dave Sutton
Asked by Anonymous on April 22nd, 2017.
As long as the second and third characters (AB) in 4AB3C1B match with the tank in your amp, you can play around with the other numbers. For example, if you wanted a long tank with 3 springs instead of two, you would want a 9AB3C1B.
Would this tank work in a Sunn SX6350 PA mixer? Thanks!
Asked by Anonymous on August 10th, 2017.
We simply do not have the resources or reference materials to determine what type of reverb tank your Sunn needs. If you have the original tank, you will want to see if there is an alpha number code on it. If you can get that information to us we might be a able to help you out.
Is this an improvement over the stock PRRI reverb tank?
Asked by Anonymous on September 15th, 2017.
Yes, we believe that the MOD series of reverb tanks are an improvement. These tanks are made as close as possible to the original USA made Accutronics tanks.

devrede değişiklik yapmam gerekiyor çünkü alıcı kısım zayıf.
neler önerirsiniz sevgiler.

The 4EB3C1B has a long decay time, so finding a reverb tank with a more lush sound may be as simple as replacing a weak or defective tank with a new one. The MOD brand tanks are highly regarded in the industry and you can view the 4EB3C1B at the link below:
Is this the longest decay plate for a 60's fender deluxe? Reverb Tank - MOD®, 4AB3C1B
Asked by Anonymous on September 4th, 2018.
Yes, this is built with the longest decay time for reverb tanks.
Just installed a mod long delay 3 cone in a hot rod deluxe and reverb knob is maxed out still not enough reverb?
Asked by Anonymous on April 22nd, 2020.
According to our records, the 4EB3C1B is the correct tank for a Hot Rod Deluxe, not a 4AB3C1B. This is most likely what is causing the issue.
My friend has a 72 vibrolux and bought a MOD®, 4AB3C1B, Long Decay, 2-Spring reverb tank and was wondering if it needs a bag. He bought one but is unsure how to mount. He just doesn't want to mess anything up. It belonged to a friend that passed away and he is re-doing the amp. Does it need cardboard and bag or just mount it? Thanks....Troy Hollinshead
Asked by Anonymous on June 9th, 2020.
The bag helps reduce unwanted noise and feedback, while the cardboard helps to keep the mounting holes lined up properly and also helps some with noise. Technically they aren't required, but it advised that you use them.
What tank do I need for a 79 twin reverb and a duel showman reverb early 70 Thanks ,Shaky
Asked by Anonymous on January 12th, 2021.
We aren't able to confirm both the Twin and the Dual Showman use the same tank, but the Twin Reverb uses a 4AB3C1B tank like the one in this listing. It is likely the Showman does as well, but you will need to remove the original tank and inspect it to confirm that.
What is correct reverb tank for Fender Supersonic 22? I don't know the exact year.
Asked by Anonymous on February 23rd, 2021.
The 4AB3C1B tank is used in many Fender tube amps with reverb, so this is likely the right tank for your amp, but we do not have information on the Super Sonic 22 specifically to confirm that. We suggest removing the original tank and visually inspecting it for a tank code to verify compatibility with your amp and this tank.
I got a MOD 4FB3A1B tank a little over a year ago for a project I was building, and its worked fine. As you know, this model is designed for installation on the floor of the cabinet. I’m thinking of changing its position to horizontal on the back of the front grill of the “ReVibe-Type” cabinet I have and wanted to know if that’s something I can modify in the tank or not. I really don’t want to get another tank. Also can I change the impedence of this tank. Its now being used with a tube driver and I might use it one day in an amp with a reverb transformer and so I would need one with a lower impedence.
Asked by wsscott72 on March 23rd, 2021.
We are not aware of a way to alter those two particular specifications in a reverb tank.
