You can always try with recorder, lik one of theseAnd then You mix sound with video :)

This Gretsch is probably bez choiceBut i'm in love with Guild, so I can recommend You also Starfire

This is probably bad G string. Try new set, like GHS or Fender

Little martin is great, but I found also nice baton rouge

For this price I can recommend You Mustang and Boss Katana

This Lag is greatBut if You need electronics, try Seagull

If you want something cheap, but good and loud, try one of theese

.

I don't know why, but some lower wattage amps can be louder than amps with more power. These are loud

This is my suggestionYamaha makes also grat classical guitars

You can try vintage instead of epi. But...i don't know. I would choose tele,like this
