I seem to be spending a lot of time (and money) at the shop with my armada of guitars, getting setups, pickup installations etc. While the folks at the shop are super pro's, they don't mind charging top dollar for their services, and taking their time getting to my orders, since I have so many, and they have other customers besides me to deal with. How hard is it to become proficient at this stuff for a reasonably intelligent, interested person like myself? Should I read a book(s) (which ones), find a class in my area (how?), search the internet, etc? What tools would I need? How involved is this? Should I just keep working with the pro's? Thanks in advance.
