Compatible with Ampeg® amps that require the original spec, type "C" reverb tank with insulated RCA jacks.

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.

5 out of 5

A good replacement for a Gibson, Valco, or Magnatone amp, with a long decay F tank. These are not as lush as the old Gibbs/Folded Line/OC tanks, but nothing is like a Gibbs tank. These are a bit more like an old Accutronics. Eventually Hammond dumped Accutronics for Gibbs. Gibbs was a better tank. There are maybe 3 manufacturers of spring tanks left. None of them sound quite like the originals. Mod tanks sound a bit closer to Accutronics USA, than Accutronics Asia does.
