For guitar setups I have been using this book. Covers every type of guitar and goes step by step through the process. I got the Kindle version for $4.99 and read it on a color tablet because there are a lot of photos. I knew nothing about set ups before hand and was paying $75 to $100 for them. I know have nine guitars and do them all myself. Not a bad return on the $5 investment. Plus I learned a lot about my guitars and can fine tune to my liking.
