Well, I recently got a WT550 and this weekend I took it for practice with my band. Everyone said my tone had improved etc but I noticed this: the volume was a bit less than what I wanted (we play loud), and I didn't turn it up because the "output limit indicator" would light now and then and I didn't want to damage the amp (the manual says that this light indicates that the amp has reached its max output level). I was using a passive Warwick, Gain at 1 o clock, eq flat and master around 1 o clock. I pluck kinda (too) hard. My question is, could this really be the output limit of the amp? At one o clock? I know it's not the cab because it was an 810 800W Ampeg. What would happen if I turned the master at 3 or 4 o clock?
