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.

Product Reviews
I've had a Limited edition (12 inch alnico speaker) '65 Princeton Reverb re-issue for about a year, and, though I really love the tone of the amp, I never wanted to add any more than a tiny bit of reverb because the factory unit had an irritating flutter. I replaced the original 2-spring short decay tank with this 3-spring long decay unit and the improvement was dramatic - a smoother, fuller sound. The swap was easy, but I did notice that the color code on the input and output connectors was different from the original, so make sure you connect your new tank using the in and out labels as your guide. Thank you, Amplified Parts, for having such an informative web site.
Good sound. better than Accutronics.
I attached it. tube spring reverb(guyatone FR-3000V)
