He did have a Bag End cab behind him, which I assume was a house cab (since the entire PA and monitors was Bag End in this club). Definitely all the sound to the audience was coming from the front of house though. He did have his volume pedal hooked up, but never touched it. From the massive low end, I would not be surprised if they had an ELF system going on with the subs... just guessing there.
He had some strange looking unit on top of that backline Bag End cab, but didn't look like it was on (no lights). About the size of an LMII, brushed aluminum or steal case, long, oval 'black' sort of front end, no knobs/no lights. Maybe a power amp driving that Bag End for personal monitoring.
Interesting that he did two extended solos (Anthony typically does not solo from what I understand). Very complex, chordal solos, using the WHOLE range of the instrument.
I REALLY dug the tone. That 'passive P Bass' when you really hit it sort of aggressive upper midrange grind, but combined with massive, clean, open low end. Really something.
