I put P-90 style pups in both positions. Replaced stock bridge with cheap roller. Replaced stock tuners with Planet Waves locking tuners. Moved the postion of strap pin from side of body to behind where the neck joins the body as the original position caused guitar to become too neck heavy for me. Ordered a Chet style vibrato arm as I have one of these on another guitar of mine and really like it. Oh yea, I also applied some improvised fret markers cause I don't like playing with just thumbnail style.
