I have spent some time with this guitar, cleaning and setting it up, and I have also investigated some history behind from the owner I purchased it from. According to the wife of the original owner, the husband was quite the tinkerer. This Starfire was fitted for the LARGER GUILD HUMBUCKING PICKUPS sometime in the early 70's. Not the perfect job, but certainly could be cleaned up. Because of this, the pickguard, original or not, was modified to fit the larger humbuckers. At this time, the knobs were replaced with 70's era Guild knobs (no VOL or TONE script on the knobs skirt). The INPUT JACK has also been reinforced with a metal jack plate. Beside an extra screw hole, it doent show damage from the previous input jack. The only surprise I found was the presence of stop tail holes underneath the Guild Bigsby as shown in pics. A professional job, but I was unable to find out if this work was factory. But please folks, expect to play this thing not expect it to be a collectors piece!! It has cleaned up nicely, the NECK IS STRAIGHT, FRETS are Great, save minimal wear to first 3 frets. NO GOUGES IN FRETBOARD. ALL ELECTRONICS WORK PERFECTLY!
