1: Does anybody know a lesson where they show you how to make a good rock sound on your guitar? I want to have a rock sound on my guitar but I don't know on what level my treble, bass, middle, gain and volume have to be! Maybe you guys know?! I'm playing in my bedroom. If you get a good rock sound on your amp in a bedroom I want to know how you made that good sound. Please let me know how high or low your treble, bass, middle, gain and volume are? Appreciate it

2: What means when they say "single coil guitar"?
