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.

I put this replacement Reverb tank, in a Dr Z EZG-50, it sounds really good, very very deep and swirling reverb sound, with a little less tail, then the original tank. It's also built a lot more sturdy, then the other tank, the transducers seem more solidly mounted and the cable jacks are riveted to the body of the tank, making them much more solid. A VERY NICE TANK, for the price, and VERY FAST shipping. GREAT JOB GUYS.

Had a repair to do on a Dr. Z amp. Turns out the reverb tank was defective. I read a review about this MOD tank as a replacement and the great sound it has. I was pleasantly surprised at the great price and quick delivery. I installed the tank and it was an amazing difference in the smooth sound of this tank. If you need a new one this is a great product for a great price, even with the exchange rate to here in Canada.

I installed this in a Mesa boogie studio 22, to replace the internal unit. Worked like a charm, sounds very rich, plenty of 'verb.

This reverb tank is a direct replacement for the stock unit in a Dr. Z Maz 18 Jr. It was a cinch to install and it sounds fantastic. AES is a breeze to deal with. Price was fair and I received the unit just a few days after I placed the order.

Questions and Answers

Hello Can you use this tank to add reverb to an amp head that didn't come from the factory with reverb? To make things more difficult, I have an amp not listed in the item description(DV Mark Triple Six 40 watt). If it's reasonably possible in theory, I'll then speak with DV Mark Amps and find the right match as far as size, springs, Ohms etc. Thanks1 answers

If your amp does not contain a reverb circuit then the tank can not be added without extensive modification. I would suggest contacting the builder to see if this is a viable option.

Will this work to replace a 4AB3C1B? The ohms are not exact but close. I'm looking for a shorter reverb time. Thanks.1 answers

Our understand is as long as the second and third character are the same, you can swap tanks to get difference specs.

We are not sure if this will work with your Mesa Boogie. You need to find out what reverb tank you currenty have. The second and third character in a reverb tank number designate the input and output impedance. You need to make sure you pick a tank with the right impedance.

We are unsure if this will work in your Dr. Z but we have some pointers to help you out. Always pay close attention to the series of letters and numbers associated with each reverb tank. In this case 8AB2A1B. If these numbers match your existing tank then this replacement will be compatible. You may want to contact Dr Z directly for tank options.
