Yes and No. The tone needs to be right within the band mix context, so adjust your main band presets at home first, then maybe tweak them while you're playing the song...? I used to set up a few presets that were slightly different, then change them during a song to see which sounded better, so as to not waste rehearsal time. That's a tough one, imo, because a preset that sounds good alone, may need further tweaking to sound better in the mix. This is where experience really helps.What about tweaking their settings because there was just a "new firmware" release??
