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 have a 1968 SUNN Solarus amp head that I'm restoring. Someone removed the reverb tank and cut down the box approximatley 3 inches. I made a new box with the proper dimensions (24"x10"x10") installed new MOD reverb tank and new RCA cables and she's back to her glory. Thanks

I installed this tank in a silverface Princeton Reverb. The original Accutronics tank had dropped a spring when a transducer broke, and sounded terrible as a result. This tank has a longer decay than I think is typical of vintage Fenders, but otherwise sounds great! Full-on surf sounds are there if you want them, as well as more moderate settings. Installation is easy! I'm glad I did this.

Mine was loosely shipped in a bigger box with my other items. It failed after about 3 hours use. AES had me ship the defective one back which cost me more than buying one...
Now I have a two week or so wait for another tank to arrive and a customer without reverb in his amp. The tank did sound pretty good while it lasted. I could have bought one locally and will probably have to for this customer.

The MOD tanks sounds smoother and warmer than my Fender Twin's original (2005) Accutronics tank. AES was fantastic as usual with shipping; careful packaging and a quick delivery!
