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.

Hi, this reverb tank is 16 3/4" in length. I would measure your amp to make sure you have enough room.

This is a long tank at 16 3/4". You will want to measure your existing tank to insure a proper fit. Regarding compatibility, we are unsure if this is compatible with your amp.

All of our records indicate that the Nashville 112 used a 9EB2C1B, but we can not verify that has changed since production moved to China.

We do not have reference materials to confirm the tank used in that amp, but this tank is used in the Classic 30 as well as the Delta Blues, so it is likely the correct tank. These are also a direct replacement for the Peavey tank #71011114 so if that is the tank currently in your amp, this will be compatible with your amp.

I bought an oversized Blues Jr. guitar amp cab and wanted to put a full sized tank in it. After reading some reviews, I decided to buy the MOD 4EB2C1B and give it a try. I like the connectors they don't look cheep like the new China Accutronics tanks use. It looks like the OEM parts that are in my old Accutronics tank in my other amps. The sound is very clear and balanced. It sounds better than my old tank so much so that I am buying another and replacing the Accutronics in my Hot Rod Deville. Totally happy!

Bought this unit to replace the Accutronics tank in my Peavey Classic 30. There was nothing wrong with the stock tank, but wanted to see if there was any improvements. Definitely improved with fuller sound and slightly lower noise floor with higher settings. For 20 dollars it's hard to go wrong with this upgrade, both clean and overdriven sounds great. Great customer service and super fast shipping. Thanks!
