Based purely on quality of tone for a hard rock band, which would you prefer? Stage volume isn't really an issue, but I want the best tone possible. I'll be playing thru an Ampeg 8x10, with a StingRay 5, with multiple effects in-between. Just looking for a nice warm, sometimes crunchy sound. I already own a GK 700RB, so I know what I'd be getting from the GK. Just wondering if taking the plunge to Ampeg will be worth it.
