I don't remember what's on there! String experiments would be a whole lot more productive if I kept track of the strings. But, I don't. So it's always all new. I know for sure I like slightly heavier Bass Burners on the Flamingo. That's settled. The pixied dust 2001 will probably end up with Cobalt Flats, more or less permanently one day soon. I like Black Beauties on the bolt-on and the Fenderbird. The bolt-on currently has uncoated rounds, and it may just keep them. The '15 has uncoated rounds for now, but I think tapes would suit it well. I found that I could get a whole lot of different sounds that I wasn't expecting when the Flamingo had tapes on it. Angry piano? Yep, a hint of that when really digging in. They are more versatile than I had expected them to be, and on the '15, they ought to be even more versatile.
