Hi everyone, I just purchased a GK 1001RB and although it sounds great, it's not me and it doesn't fit in with my band. The Ampeg sound fits perfectly. I've been using a mid-70s SVT which stopped working. I'm going to get it fixed, but I don't want to take that thing out of my house anymore. So it's time for a replacement. I'm about to return the GK and get the SVT4. I've used the SVT4 live and it sounds great and I can get a sweet deal on one. The only thing stopping me is that I heard that the Mesa Big Blocks are some of the meanest sounding amps out there. No Mesa dealer here stocks those models. Does anyone have any experience with the Big Block 750 or the Titan V-12? I know only Ampeg will sound like Ampeg, so you Mesa users, should I go for the Ampeg or will the Mesa crush it completely? THANKS!
