I made 3 major changes to the guitar:
1. installed a Lollar Chicago Steel 6 string pickup. The Lollar PU fit the body opening just fine, but it was a little too wide to fit up inside the palm rest. I use a flat bastard file to remove about a 1/16" from each end. I'm sure that modification voids the warranty, but it didn't seem to affect the sound.
2. Replaced the plastic (and cracked) cover and palm rest with a new set from GoldTone. The cover from GT was almost a perfect fit. I just had to modify the bridge (see below) and drill some new screw holes,
3. The biggest issue was the bridge location; at 1st it was too far forward by a 1/4'. I filed the saddle area back an 1/8" and did some more filing along the edge where the strings attach. The scale length is now a perfect 25 3/4.
4. The jack cup/hole was 1" across rather than the typical 3/8" of Tele jack cups. I substituted a square Gibson plate (1-11/32") which covered the hole & matches the new chrome cover.
Very little of this guitar was original, so I didn't hesitate to modify it with newer parts. The rejuvenated Oahu sounds and feels great. It was a fun project.
