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 do not have cross reference materials to verify what tank was used in that amp. We suggest pulling the original tank out and visually inspecting it for a model number or other identifiable markings that we can use to narrow down your search.

RonSound - November 30th, 2018

Bought this for replacement in a vintage Kay 710 reverb unit. Worked great and gave it a really nice surf sound. The only thing I had to do was remove the mounting cushions and enlarge one of the holes to hold the ac cord. 15/10 would buy again.
