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.

Excellent replacement for the 2 spring tank that came with my California Tweed.
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.
Very nice replacement for my Mesa Boogie Express.
