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.

I needed a new tank for an Estey T-32 amp, same as Magnatone 432, and this worked like a champ. Perfect replacement.

These also work in the earlier Music Man models; I've put a couple into mid-70s HD-130 Reverb amps. I will say without reservation that these are made more solidly than the originals and introduce less hiss.

this was a replacement in my Zinky Blue Velvet all tube guitar amp. The part was shipped promptly, arrived sooner than predicted, and was an easy, modular install, and sounds as good than the original. Overall, a very good buying experience.
