Ok, so I bought three rack units at the same time. If I buy a DigiTech Studio Quad V2, do I really need another one? Well, you never know. Might as well get it :)
Actually, it's not exactly the same:
This is the DigiTech Studio Quad 4, the successor of the Quad V2.
I think the only thing that differs them is that there are some more signal combinations possible on the 4 compared to the V2 but I haven't really found a good comparison. So, it's a 4-in 4-out effect unit. I think I'm done with effects now...
unless I find a Lexicon... There's something about that name :)
