MOD® Reverb Tanks | Mod Kits DIY

Mod Reverb Tanks were carefully designed and researched to bring the warmth of a vintage sounding reverb to your amp.

What people are saying about MOD® Reverb Tanks:

"Longest decay rate of the three, very broad tone and is best suited for those who desire a long decay, ambient sounding reverb. Almost sounds like a large room. Lots of bottom end. Lots of hang time/dwell."

Hey Alex! The Deluxe Reverb's have the 4AB3C1B. Some people like using the 9AB3C1B for a bigger sounding reverb too.

The easiest way to identify the tank you need would be to check the original tank for the reverb code on the outside of the metal enclosure ie 8DB2C1B. If you no longer have the original you may want to search for a schematic or reach out to the manufacturer to see if they can help you identify it.

Typically when the 2nd and 3rd digits match the tanks can be interchanged. You'll want to verify that the size and mounting style will work for you as well.

The stock tank in a Blues Deluxe Re-Issue is the 4EB3C1B. Its really hard to pin down the difference since every amp is going to sound a little different but the 3 springs generally have a deeper sounding reverb.

I have a 1981 music man RP 115 with a short spring reverb that works but does not have that great reverb sound I’m looking for. Therefore, I’m hoping to change it out. My question then is this, do you have a replacement for this amp and what is the price? Thanks Terry White

Hey Terry. It looks like those amps had some variation in the tanks used. Does yours still have the original tank? Are there any markings on the chassis of the tank?

The stock tank for that amp is the 4AB3C1B. For a medium decay you'd want the 4AB2C1B. If you want to go even shorter you could try the 4AB1C1B

That really comes down to the circuit around the tank. The same tank will sound different with two different reverb circuits. A good reverb drive and recovery circuit will sound great regardless of the tank required for it.

Hello, I have an accutronics unit out of an Orange AD30R that needs replacing. 9AC1B1B. I can't find a new tank with that model number ANYWHERE. Could you recommend a different model that will work just as well. Cheers.

The closest match we have to that is an 8AC2B1B. The differences are that this one is a 9.25" short tank rather than a 16.75" long tank as well as the decay length is a medium and the code you have uses a short decay length. Everything else is a match and should work electronically but you may find that mounting it will require some changes.

Hey Laurent. Unless mods are added to give the proper circuitry for reverb driver and recovery the tank won't do you any good. The tank is only a part of what makes spring reverb work.

This amp looks like it used a different kind of tank than the ones most vintage amps use. I can't find any solid numbers on the impedance requirements. It might come down to experimenting with different tanks to find what works best for it.
