I did a little Google searching, trying to figure it out. not much help. It appears that it's multiple reasons. And I'm assuming they're very good reasons. Can anyone run down the top 3-5 reasons . This guitar has "2 pieces of alder selected for low weight" for example. Somewhat clear to me that I definitely prefer lightweight guitars for playing for long periods of time. However I had a 13 pound Les Paul that was the biggest most powerful sounding guitar I've ever owned, massive sustain. Massive low back pain. it had to go. But boy do I remember that sound. So how does that weight balance with tone, I have just pulled the trigger on a 63 custom shop relic journeyman telecaster 6 lbs. 13 oz. of alder. I'm afraid it won't sustain???? (not really) question number 2, I also wonder why the threaded barrel saddles were invented it looks like they just found some threaded stock laying around and decided they should probably use it to save money? Because they were a startup company at that time.? double binding wow nitrocellulose lacquer wow threaded barrel saddles I have a feeling lightweight low density wood might open up the harmonic complexities, perhaps. Thanks for all the knowledge on this website.
