Saw Organissimo a month or so ago at Club 30 in Lansing (a week after seeing Joey Defrancesco at Cliff Bells playing the "house organ"; an A-100 rebuilt and stuffed into a BC case through a 122a Leslie). I wanted to make a comparison, but the sound in the "disco club deco" (high ceilings, tile, flat walls, lotsa glass) made it difficult. But I will say that the bass from your rig was spot on. Loud, but not overpowering, tight not booming, just great. If you don't mind me asking, what are you using for a subwoofer?
A great performance by the band, I look forward to more.
