Dude, that Melody Maker is WAILING now... sounds so good! I finally got around to changing the strings to 9's (my preference for p90s), used some DR Pure Blues. Is that what was on there? The ball ends definitely looked like DR. That helped quite a bit with getting some more upper mid clarity.
Something still wasn't quite right, so I changed out the cap, dropped in a .022 Orange Drop. Ohhhh yeah, big difference right there. Even wide open, it's just got a little more of the p90 raspiness and "sings" a little better.
Finally, I tweaked the pole pieces today. Wow! What a difference those little changes have made. The guitar has gone from

to

... Still need to upgrade those stock pots though... the tone one especially is all but useless. Just had to let you know how excited this little guitar has gotten me.
Have you decided what you're doing with the Studio and/or started any work?
