i show all of my students how to setup their guitars if they want me to. i go in depth about the physics of how each adjustments affects the guitar overall. i especially do this when i mod an axe, usually with soldering, but not limited to it.lyconxero said:Reading about it is all well and good, but unless you actually see it done for yourself then it may still elude you. I watched the tech at my local guitar shop change the strings on my RG370DX and fix the action by lowering the trem and straightening the neck all in under 30 minutes. I was very impressed and learned several things in the process (like how that stringing the balls at the headstock thing works AND that you don't have to change one string at a time).
