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.

This reverb tank was exactly what I was looking for. My Fender Princeton clone came with an Accutronics 9AB3C1B (3 springs, long decay) and it was just too much. The effect was too pronounced unless the reverb was very low and that wasn't what I wanted. I tried a 4AB1C1B (2 springs, short decay) and it was too artificial surfy to me. I exchanged and got this 9AB1C1B (3 springs, short decay) and it was perfect. I can keep the reverb prominent but the decay is exactly where I want it. Everyone's tastes will vary, but make sure to think carefully about what type of spring reverb sound you want. Unless you're playing surf guitar, probably 3 springs, and at least for me, short decay was the winner.
