Always pay close attention to the series of letters and numbers associated with each reverb tank. In this case 4AB3C1B. If these numbers match your existing tank then this replacement will be compatible. Please refer to our tech corner article explaining reverb tanks for a full explanation of what these numbers signify in terms of determining compatibility with your amp.

Hi, we believe you need a 4EB3C1B. Please confirm this by consulting your manual.

We do not have a cross-referencing database on these amps. You would need to examine your existing reverb tank and see if there is an 8 character code on it such as 4AB3C1B. Pay attention to the second and third character. These represent your input and output impedance. When replacing a tank these must match. For more information, please see our tech article on reverb tanks: https://www.amplifiedparts.com/tech-corner/spring-reverb-tanks-explained-and-compared

We are unable to find any definitive information on what tank was used in that amp, but if you remove the original tank from the amp, it should have identifiable markings that should help indicate what tank you need.

The only accurate way to test these is with an impedance meter. The readings you are getting with your multimeter aren't abnormal.

Yes, the original 1965 Deluxe Reverb (included in the list of compatible amps above) uses the same tank as the new reissues. As Fender use Accutronics tanks in their amps currently, this is most likely the exact tank that came in the amp in it's stock form.

You may want to double check a schematic but the 4AB3C1B is used in most Twin Reverb amps.

We offer a kit that uses a full size reverb tank, but it is not in a pedal format: https://www.amplifiedparts.com/products/effects-kit-mod-kits-wave-spring-reverb

Ordered as a replacement for my Princeton Reverb. Sounds lovely, definitely has the classic Fender character. Only giving four stars because both transducers were loose. Not a huge deal, nothing a drop of superglue couldn’t fix. Would recommend but check the transducers for movement before you install.
