Ehhh, the same is true at a lot of guitar stores. Guitarists believe a lot of fucking woo, in general. I’d say we were worse than the rest of the population, to be honest. Anyone involved in sales is doubly suspect.
On the other hand, if you can find a guitar tech or shop that you trust, use them. The more focused they are on setup/repair, the better. I live in a large metropolitan area, but there’s only one place that I trust to set up an instrument better than I can*. Even if I was unclear in my needs in the setup, they will take me in the back if I’m unsatisfied when I pickup the instrument, and even shave/dress frets while we talk to make sure it is to my liking. The same shop has performed a complete re-wire, re-nut and re-fret of a crazy Italian guitar for less than you’d pay to buy a decent guitar from the far east. Seriously, if you like guitars, find a good repair shop to do work that you can’t figure out. If they’re good, they can turn a pile of crap into a playable instrument.
But drad dog and Ranger Jeff hammered home one thing I agree with hardcore: learn your E/Em A/Am barre chord forms as soon as you can after learning your first song; and understand what makes them an E, or a G or an A depending on where you put them (hint: root note). Work to understand why they’re different, and why you would choose one over the other in context. You can play a phenomenal amount of songs only understanding what a I-IV-V change is, and that’s with only major chords. Once you know how to throw a minor in, and where, then you have the beginnings of fun.
OTOH, I don’t agree with a chord dictionary. I think access to one stunted my musical growth. If you can figure out why a major, minor, 7th, 9th, etc. chord are constructed the way they are, you can figure out how to construct any chord under the sun, plus learn other fun tricks such as inversions and substitutions.
But, that’s all nonsense ahead of you. Get those fingers toughened up with the chord changes to “Angel of Harlem”! Then learn to play it with all barre chords! I learned with the strings a half inch off the fretboard, and so should you!
Ok, I’m jealous that your Yamaha kicks the crap out of the Global I learned to play “Amazing Grace” on. Ignore me.
