MOD® Reverb Tanks

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.

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.

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.

The closest we might have is the 4FB3D1B or the three spring 9FB2A1C. None of the tanks we sell have the locking mechanism which is digit 6 of the code. The 5th digit on these tanks is also different meaning that the input and output have a different grounded/insulated setup. This is easily modified by jumping or desoldering two solder pads. The 2 spring tank has a different mounting plane designated by digit 8 of the code.
