We live in a golden age of good quality, inexpensive guitar equipment. You can buy perfectly adequate starter guitars or amps for $200 from any number of manufacturers. You can improve amps with speaker (and/or tube, if you go that route) swaps, but I don't think a new guitarist notices those shortcomings right away. The
Boss Katana is worthy of consideration. You get Boss' entire lineup of pedals to assign, it's plenty loud, lightweight, simple to operate. If you'd rather try tube amps, a good basic one is the
15W Monoprice. These go on sale all the time, but they also sell out quickly, on-sale or not. At this stage of my development, I prefer an amp with preset voices, and I like those offered by the Fender Super Champ X2 and the VOX AV series.
I still like to experiment with string gauges and types, but prefer D'Addario as a manufacturer. I was surprised recently when I discovered a pick material that I could hear make a difference in my tone:
Dunlop Ultex. Try out different straps, too. A comfortable strap is worth the money, and a bad strap will keep you from playing.
