Hey guys, I recently purchased a new Ac15c1, and like most people, I'm not in love with the reverb. The consensus seems to be putting in a MOD 8EB2C1B reverb tank and taking out the stock one. My question is, how exactly does this differ from the stock tank, or is it simply a replacement? A silver colored Belton BS3EB3C1B dated 2014.07.25 is what is currently in the amp. Thanks!
