This lesson's mostly for people hoping to buy an electric guitar. If that's not you, you may want to skip this lesson.
I recommend going to a guitar store and see what you're drawn to. Fender and Gibson guitars will be of higher quality, and Squire and Epiphone are their cheaper counterparts. There are lots of other good manufacturers too.
Fender Mustang 8" Speaker: Tons of effects
Peavey Backstage II 6" Speaker: Simple
Fender Blues Junior 12" Speaker:Simple, bigger, louder, and higher-quality.
Celluloid Picks made by Fender and many other companies are standard. They're fine but the thin ones break easily.
My favorite is the Dunlop Nylon Standard .88 pick. It has a grippy surface and won't tear like the celluloid picks.
If you struggle with holding on to your pick, Cat Tongue Picks are the grippiest I've found.
The Kyser Quick-Change capo is my favorite because I can stow it on my headstock.
If you have a smartphone, get GuitarToolkit. By far the most accurate tuning app I've tested.
If you want a dedicated tuner you can carry in your guitar case, the Snark is accurate and popular. Like the Kyser capo, you can stow it on your headstock, and since it works by sensing vibrations in the wood, you can use it in noisy environments. Its main drawback is that it only has a "All Notes" mode, which makes it less beginner-friendly.
