Replace the Behringer 2600 Grey Meanie Reverb Tank with a Proper One!

Tank from an old Fender Amp replaces factory unit. (Wait until your 2600 is out of warranty). Mod is easily reversed. Practical cautions apply for electrical etc.
This tank is labeled: 4AB3C1B.
I don't know if this works for the Digital reverb but I would guess not.
