The MOD® 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.

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.

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: https://www.amplifiedparts.com/tech_corner/spring_reverb_tanks_explained_and_compared

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 would suggest an internet search and perhaps someone else has upgraded their Crate tank to a MOD. Beyond that we would need the numbers from the existing tank and perhaps we could find a solid replacement.

From what we could find from a brief internet research it appears as though this is the correct reverb tank for your unit. We always suggest further independent research to back up our findings as we are not techs.

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.

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.

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.

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.

From our limited research it appears that the 4AB3C1B was the original tank in your amp.

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.

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.

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.

Although we have not been able to verify this information, our customers have reported that this is the correct tank for the Supersonic 22.

Unfortunately, we are not techs and can not properly diagnose the problems you're having with the amp. We recommend taking it to a qualified repairman.

The 9FB2A1C should work but you will need to confirm this by looking at your existing tank to insure compatibility.

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: https://www.amplifiedparts.com/products/reverb-tank-mod-4eb3c1b

We do not advise changing the size of the tank, simply because there are no 9.25" and 16.75" tanks that share the same input and output impedances.

Chris R. - August 1st, 2018

Replaced the stock reverb tank(accutronics) in my 2000 "the Twin" as I felt it sounded worn out. The Mod reverb tank sounds great & has given my amp new life.

doguitar - December 1st, 2017

This tank is a direct replacement for the "Accutronics & Belton 64063" tank in my Fender Super Sonic 22 combo. The stock tank was acting up. This MOD tank sounds much better than the stock tank. It gets pretty surfy wet if you dial it up.

sfrrog - February 11th, 2017

Great Reverb tank. I bought it to replace the unit in my new Fender Super Sonic. The Mod I received was exactly what was in my Fender SS. No difference at all. Check your amp before you decide to replace the tank. I thought I was buying an upgrade but it turns out I didn't need it.

plumberabe - January 18th, 2016

Better than factory. Very pleased (94 twin)

D.W. Dezern - January 5th, 2016

Replaced bad tank in Fender Super Sonic. Now she's right for the first time. Sounds great. Better than factory tank. Now she sings,cries. Price was great. Delivery time was great. Thanks AP. I have my amp back.I give you 5 stars !

SoCal323 - August 14th, 2014

Bought this to replace a broken accutronics reverb tank that originally came with a recently aquired used Fender Deluxe Reverb Reissue. I have to say that I am extremely satisfied. It has a nice full decay and leans towards the bright side of the spectrum. The decay is nice and smooth without any "echo" type effect. Only time will tell how long it will last but for the price, It's as good as it gets. I would recommend this tank to anyone looking for a bright, smooth, and long decay in their reverb.

jke - March 1st, 2013

Direct replacement for the tank in my late 70's Ampeg VT-40 combo. Great value.

June 6th, 2012

Replaced both tanks in my Mesa Boogie MK2C and Mesa Express,

these replacements are better made and offer a better sound overall than the original Accutronics and cheaper!

Great value, buy one!

August 11th, 2011

Replaced the verb in a 80's Peavey Backstage. This reverb is far superior to the stock one. Nice size...fit perfectly. Very smooth sounding.

June 1st, 2011

Great price, got it fast, My Fender Deluxe has reverb again. It fit right in the bag, plugged in the same way, done deal. Thanks Amplified Parts.
