The Mod Electronics 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 what tanks goes in the ML Deville. But this is the tank used in the Hot Rod Deville. You may want to look for a tank number such as 4EB3C1B.

This is most likely not compatible with your amp. You will want to look at your tank and determine what the tank code is. For example, 8EB2C1B is the tank number for the AC15CC1.

With differing input and output impedances, we would not advise replacing the stock tank in your amp with this tank. You can refer to the spring reverb tanks explained and compared tech article so see what each character means as well as what can be safely altered and remain in spec.

It may fit, but the studio pro has a short two spring tank in it originally, so it would not be the direct replacement.

Bought for Fender Hot Rod Deluxe in which The Accutronics reverb cut out intermittently. Sound is ok but not better than that unit. Useful up to about 1.5. Above that it gets pretty harsh. The Accutronics one was ok up to about 3.
