The MOD Reverb Tanks are high quality upgrade units. Some of the major differences between the MODs 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.

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

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

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!

Excellent alternative to some of the, ahem...other tanks out there. Pop this in your amp for a warm, authentic sounding reverb. Highly recommended!

These tanks are really great. A lot more "drip" than most new production tanks. The sound is also smoother and warmer with a bit more decay. Highly recommended!

Got this reverb tank to replace a broken Belton/Accutronics 4AB2C1B tank in a B-52 AT100 head. This unit has a little longer decay time.Works and sounds great, lots of sound to work with.Affordable and highly recommended.

Tank works great with a 1965 Fender Twin Reverb, 1967 Pro Reverb, and 1977 Silverface Twin Reverb.

Replaced a broken stock unit in an 83 Fender Concert 2x10, I put a Fender replacement in (taken out of another Fender) sounded Good. This one went in and WOW all I can say is Great, Warm,Round and alot more. No need to go above half way.
