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.

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. For more info please visit our article on reverb tanks here:

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

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.

According to Fender you need an 8EB2C1B.

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.

We do not have sufficient cross reference materials to verify what tank is used in that amp. From the limited information we could find, the fist number on the tank should be an "8" and the final character an "A" but do not have the crucial input and output impedance information. This may be obtained by taking the tank to a tech.
