There's a used GL3300-24 at the local music shop out here and the faders are still extremely light to the touch. I'm not comfortable with that -- seems like an accidental nervous twitch of the finger will
send someone's mic soaring and blow out the audience's ears (not to mention your speakers).
One other thing I noticed while looking at the auxes on the GL3000 and 3300 was that even though they are 8 aux / 8 grp, your outputs are limited on groups 1-4 ... only one output
jack per aux/group pair. That means the other one of the pair doesn't have it's own output -- it needs to either go to matrix or to LR. Since I'm running 8 output channels directly to speakers this would be limiting to me. If you are running only LR or
LCR then probably not an issue.
