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.

This tank replaced the noisy original one in my 1971 Fender Vibrolux Reverb. The old one had a very loose spring that constantly chattered and crashed making it unusable. This new MOD unit is well made and installed easily. Mounted on the original backing board, wrapped in thin bubble wrap and enclosed in the vinyl reverb bag, it is well isolated and very quiet. Every tank has it's own sound I've come to know, and this MOD unit has a rather dark tone with slightly rolled off highs, not bright and drippy like some reverbs in other Fender amps. Oh well... nonetheless serviceable and a good sound as it is but not the best I've heard. Thanks AES for helping me get the right tank

Very rich reverb, maybe a bit too rich but hey, who's counting seconds???? You can always turn it down! Very nice! Best alternative since Accutronics went overseas. Great value.

I was refered to this reverb tank as the one to get from an over qualified expert.
Unfortunately, this one does not sound good and the reverb is much too long and not pleasant.

Great sounding reverb pan that I really like in my Vibroverb that I built; not overly splashy, and has a little darker tone than other standard Fender replacement (which compliments your guitar tone, especially if you are using a Tele with a bright tone because the reverb does not amplify with too much treble like older style pans). In addition to the sound quality, I must also add that the pan is constructed very well, and the flat black finish looks more professional than gloss finishes on other pans.
Finally, I also like that this reverb pan is very affordable making it a nice addition to an amp build or for a replacement / upgrade of another amp. Very happy, and I will buy more of these for my Fender builds.

This reverb tank is outstanding. I put this unit in my 63 reverb copy I built. And I was blown away at the sound and quality. I played this through my champ copy I made and am well please to say the least . Good job Mod!
