I was fortunate to see Sir Paul McCartney's performance in San Jose, CA last night. It was really a great show (my wife got the tickets through an associate at work, so had I had to cough up the $500 for a pair it might have been harder for me to say that). In a world where American Idol will make you a superstar (not!) it's amazing to see somebody whose so talented that superstar doesn't seem to be quite enough.
Well, the reason that this posting is in this thread is of course because of his stage bass amp. He played his Hofner bass about 60% of the show with a long acoustic guitar set, some piano, and even a couple of songs on electric guitar. There was a long row of stage amps across the back so it's a little hard to tell exactly who was playing what (there was a guitarist, another guitarist who switched off on bass, the keyboards/musical director, and Abe Laborial, Jr. on drums who looks like Donkey Kong when he's playing).
Sir Paul's main bass rig looked to be a pair of Mesa Boogie Bass 400+ amps. The stage speakers were a pair of Boogie bass cabinets, one with 2-15s and the other with 1-15 on the bottom half and 4-10 on the top half. These were the older Boogie RoadReady cabinets which they made for many years but are not like the current ones (black grilles instead of chrome). I think the combo cabinet must have been custom made, as I don't remember ever seeing that configuration before. That's the advantage of being Paul, I guess.
There was also a large double Vox rig next to that with large cabinets but the speakers were not visible through the cloth (this may have been a guitar amp). There was also a double Ashdown setup that looked to be a 15 and some 10s.
Sound was great, but had nothing to do with the stage rigs I'm sure. The venue (HP Pavillion) is notorious for really poor concert sound but this wasn't bad at all. Paul is a fantastic bass player, which is all the more impressive when he's simultaneously being a fantastic vocalist on top of that.
The light show and stage design was just amazing, really superior to anything I've seen before. There was a wall of video displays across the back of the stage that wrapped down under their feet and covered the entire stage floor. Above that there was an even larger wall that had a bank of spotlights, projectors, and rollaway screens. They would have a light show on the screens or would pull them back to create an effect like an uncurtained theater stage. Really cool.
