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.

All of the technical specs are identical aside from the way the two tanks are mounted, so it should work however, you may want to lay the open side down on the bottom of the cabinet for peak performance.

Reverb tank tone is subjective and some may feel that is true while others may disagree. We have made a video series comparing a number of different tanks that you can view here: https://www.youtube.com/watch?v=c1IIiv89Qoc&t=68s
