Someday, and today is not that day - but you can read about it elsewhere, I'm gonna write about Paul Reed Smith. We share some similar understandings and I value quite a bit of his work. However, they're generally (the better ones) out of reach of the usual guitar player. At the same time, I'm confident in saying they're worth the money. Basically, a guitar is subtractive. You put x-amount of energy into the guitar, and it transfers x-amount of energy out of the guitar. The things that you add to a guitar all subtract energy from the amount that exits the guitar. You will never get out of the guitar the same amount of energy you will put into it - but he'd like to get it as close as possible. It's kinda warped, but it's his philosophy for building guitars. I strive for absolute faithful replication. I don't need additional complexity, constant change, or additional concerns - definitely not concerns with my kit. I can wrap and tune pretty damned quickly. I can do two guitars and smoke a cigarette - and chug a beer - in a 15 minute break. I also don't break fucking strings! I use the right tool for the job and take multiple guitars on stage. I've been doing this for years. I know pretty well how much force I can use. Thus, I have no need for a locking tuner. Even when I have them, I tend to wrap them normally and then figure I'll just lock them if, for some odd reason, I'm replacing a single string in a hurry. That does't actually happen very often.
