I'll mail them...
I'm currently comparing the V12 against my SVT 4 pro. You guys might think I'm crazy but to me the V12 does not bury the ST 4 Pro at all!!!
The SVT 4 Pro is actually way more massive in the lows, and remains quick and clean. I feel the V12 is actually pretty shy compared to the Ampeg when hitting the B string.
I'm tweaking the V12 EQ all the way to convince me I'm missing something, but every time I plug my bass back in the Ampeg, it's night and day.
The V12 is lighter and has way more features. But tonewise, the SVT4 is way more massive, clean, quick, dynamic and more headroom and warmer!
