Tremoverb ground switch?

[DCStreet]

I recently purchased a used tremoverb head and noticed there is no ground switch. It specifies there should be one with the manual i received. Anyone know if they added or subtracted the ground switch on certain models or what years...thanks

My old Tremoverb , circa 92-94 had one, the one i bought this month doesn't have one, but it sounds as good as the older model, it sounds fantastic.

Anyway, if someone is selling a 92-94 circa Tremoverb, just let me know, i think i might grab it too!

Don't ask me why,i love these amps!
