Product Description
Manufacturer Part Number: P-RMOD-4DB2C1D
Compatible amps include Marshall™ JCM800 (select models) Marshall™ Valvestate (select models). Can also be used as a replacement/upgrade for the smaller tank in Fender® FM210 and 212 models.
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 a bad reverb tank in a Fender 112 plus amplifier. This was a direct placement and took about 5 minutes to complete. I was impressed with the sound and functionality of this reverb tank and I’m very happy I bought it. Brought the amp back to life and sounds great!

La construction semble trs srieuse. L'installation sera raliser avec des vis amortisseur. La bande passante est trs troite (environ 8Hz) avec le pic 97Hz. Pour une tension d'entre de 4,24V on obtient 144mV en sortie. Je verrai plus tard l'impression acoustique (vintage?)

1982 Peavey Backstage 20 - old pan faded away amp; died. Got this one which replaced the old 4EB2C1B perfectly. Was concerned that footprint might be smaller - or - 2 springs vs 3, but can confirm: works great, plenty of splash on tap, and very useable range with full rotation of knob. Total winner, would recommend.

I used this to replace a broken reverb on Peavy Blazer. I followed a YouTube video to modify it properly to connect to the amp, and it works nicely. It's very good for the price. This may be an issue with the Peavy, but the reverb only seems to work between 6 and 10 on the dial. The sound is full and pleasant, with a traditional spring reverb sound, and the decay can go pretty long, with the mix creating some big atmospheric tones.
