The bridge, nut, and winding of strings are done by a luthier. Besides goin out of tune when i do huge bends, my guitar's intonation is in a bad shape. I coudnt do chords past the 8th fret. Im gonna have it re-intonated again by the luthier since it supposedly under warranty. Sayang yung tone ng guitar. I havent tried a $200+ guitar yet but mine sounds really good. I feel that investing on better tuners, nuts etc is worth it. But i dont think i wanna change the pups for now, i think they sound good as it is.
