The preceding several tours of this formation, Tony was playing his yellow Stingray, his Stick and an NS Designs EUB, though a Kemper profiler. Last night, he was playing a different 'ray, had no EUB, and had some kind of rig he was controlling with what I think was a iPad or other tablet on that stand, and he was fussing with it a lot. Normally, he's got a nice characteristic sound in the mix, not bright, but with enough low mids to have some texture. Last night, the bass was surprisingly muddy, and the Stick, as you say, was inaudible when he first plugged it in, and also EQed to deliver essentially only low bass when he turned it up. Stuff I notice as a bass player, but which didn't ruin the musicality of the concert.
