I recently got a Yamaha RGX821D; apparently the dearest of the entire RGX line in the 90s. I scored it for $280 and I thought given what it is and the condition it is in that I got a really good deal. However, there was horrible backbow and then the truss rod was completely loose. The buzzing in the middle was horrible especially under high gain and it was all just a complete mess of a guitar. It was a shame because I finally found the Yamaha I always wanted and then I ended up getting a bad one.
But I felt there was nothing left to lose so I searched some ways to bring a neck like that back from the dead and so I did the following: I put a straight edge over the neck and then clamped it right in the middle where the bow starts. I then took a clothes iron that's basically maxed out in temp and then left it over the straight edge for 20 minutes, moving around the neck as needed. I then let the neck cool down while clamped.
And voila! The neck was dead straight when I got it out. With 10-46 strings on tuned at E standard, I was able to get about 1.5 full turns worth of truss rod in there to get it to its ideal relief. I have more than enough quarter turns just in case I want to bring it down to 9-42s or something. Plus I think it will continue to bow forward as time goes by (hopefully not backwards again like some people claim after a heat press job like that).
It plays like a dream too! The neck is kind of in between an Ibanez Wizard and Wizard III in thickness so it is very thin but it very round like a Fender C. It's quite comfortable for me and it's quite a nice change from the Wizards that I have. The five scallops from frets 20 to 24 are pretty neat too! The stock pickups sound amazing; loads of clarity and balls even in high gain. I wouldn't need to replace these in a heartbeat.
Overall, I'm satisfied I got this. Sure, it was a rocky start getting it but at least I learned how to fix a warped neck like that. And then I got a nice guitar as a bonus.
That flame maple veneer at the top and back though!
With the gang!
