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.

Replaced the stock reverb tank(accutronics) in my 2000 "the Twin" as I felt it sounded worn out. The Mod reverb tank sounds great & has given my amp new life.

This tank is a direct replacement for the "Accutronics & Belton 64063" tank in my Fender Super Sonic 22 combo. The stock tank was acting up. This MOD tank sounds much better than the stock tank. It gets pretty surfy wet if you dial it up.

Great Reverb tank. I bought it to replace the unit in my new Fender Super Sonic. The Mod I received was exactly what was in my Fender SS. No difference at all. Check your amp before you decide to replace the tank. I thought I was buying an upgrade but it turns out I didn't need it.

Bought this to replace a broken accutronics reverb tank that originally came with a recently aquired used Fender Deluxe Reverb Reissue. I have to say that I am extremely satisfied. It has a nice full decay and leans towards the bright side of the spectrum. The decay is nice and smooth without any "echo" type effect. Only time will tell how long it will last but for the price, It's as good as it gets. I would recommend this tank to anyone looking for a bright, smooth, and long decay in their reverb.

Direct replacement for the tank in my late 70's Ampeg VT-40 combo. Great value.

Replaced both tanks in my Mesa Boogie MK2C and Mesa Express,

these replacements are better made and offer a better sound overall than the original Accutronics and cheaper!

Great value, buy one!

Replaced the verb in a 80's Peavey Backstage. This reverb is far superior to the stock one. Nice perfectly. Very smooth sounding.

Great price, got it fast, My Fender Deluxe has reverb again. It fit right in the bag, plugged in the same way, done deal. Thanks Amplified Parts.
