I have a big session coming up and, as a treat, I decided to splurge for a set of Pyramid flats. I usually use the Labella James Jamerson set (.55-1.10), but I've recorded on a few basses with Pyramids and they sound nice. The shop I ordered them from said that they were gauged .50 - 1.05 so I figured I'd get the bass set up as well. Well, I plopped out the big bucks for the buggers, paid for the set up and they were way too light. I had my man check it out and he said that they were gauged .42- .98. Anyway, I had to go get a new set of Labellas and pay him to set my bass back the way it was. This is how you can spend $130 on a string change. Needless to say, I'm not going to be buying anymore pyramids anytime soon. Just a warning so that nobody else who likes big, heavy flats doesn't face the same situation. That's an awful lot of money to end up exactly where I started.
