The Mod Electronics 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.

The 4EB3C1B is the stock tank for the Blues Deluxe Reissue. This tank is a compatible replacement with three springs instead of two.

The stock tank in that amp is a 4AB3C1B. We recommend sticking with the original tank model to ensure the proper input and output impedance ratings are matched.

We can verify that the 4EB3C1B was used in the Vox AC30CC, but we do not have reference material on the AC30C2X to verify. If your tank has two springs, you will want to replace it with a 4EB3C1B, if your tank has three springs, the 9EB3C1B is the suitable replacement.

Yes, the 9EB3C1B tank is interchangeable with the 4EB2C1B and does indeed have three springs and a long decay, while the 4EB2C1B has two springs and a medium decay.

The input and output impedances match, as well as all other required criteria, so yes, as long as there is physical space in the cab to accommodate this tank, this should work properly in your amp.

Yes, the impedance ratings of the tank are the most critical specs to match when replacing a tank and this should have no issues being used with a Blues Jr.

I bought this to replace the reverb unit in my Fender Blues Deluxe. The difference between the original and the MOD is like night and day. The MOD us much more lush sounds like a reverb should sound.
