I tried adjusting the truss rod on one and the racket it made put me off so I gave that borrowed guitar back and stuck to electricHello from Pennsylvania USA. I have the same proclivity for over thinking things. I work in an Aluminum foundry in the machine shop. I have played poorly for a decade or more. But I am currently electric for about 6 months. It is a whole new game than acoustic. Wow are they sensitive buggers. I enjoy Scotch Whiskey of all the whiskeys the most. Welcome and enjoy~!
