I have an HH Strat I picked up a few years ago cheap, and want to do some mods but am not completely sure of the best bang for the buck. I'm thinning out my collection and have sold 4 guitars and basses in the last two years, so I'd like to focus on the Strat and make it a great player I'll want to keep. I stripped the thick poly finish off last year and refinished from black/black to white/white. I also blocked the trem bridge, but am still having intonation issues when bending strings. I'd guess locking tuners and a new nut might be the fix, but is there any point to replacing the bridge as well? This guitar has the HH pup arrangement, and I'm not in love with their sound. What humbuckers are popular drop-ins?
