The board is one of the nicest pieces of rosewood I've ever seen. It's actually darker and denser looking than the one from my old Charvel Model 6, which was previously the nicest modern guitar I had owned (I'll brag about my vintage stuff some other time ). You can tell the previous owner (who bought it new) always kept it strung with 9's, really low action, and played it with a very light touch, as the frets are immaculate.
The Fast Track 1 is a great mate for the Super 3, and the stock middle single. If you like a single coil tone in the neck for leads, it's really fat, but still clear and works great with lots of overdrive. It's not super quacky mixed with the middle, but it does produce another usable tone. I'm going to try wiring it to split as well, so I can get that cool notch tone with the middle.
Pretty soon, I'm gonna do some more rewiring. I think I'm gonna wire a tone knob for each single coil, and leave the bridge pickup without one. I like having a tone for the bridge of my Les Paul, but I'd rather be able to leave the middle pickup with the tone rolled back, and the neck pickup wide open.
I'm thinking about trying a couple different neck pickups. I really dig the neck 'bucker tone, so I might go with an Air Norton S (single-coil sized Air Norton). The full sized version kicked ass in an RG470 I had a long time ago, so I bet it would sound good here, too.
The other one is the Chopper. I've heard Bumblefoot use it, and it sounds fantastic. Of course, he's Bumblefoot, and I'm me, so that might have something to do with it
If I do go with either of those, I'll stick the Fast Track in the middle, and have a totally killer setup.
