Watch the Billy Gibbons online guitar lesson by Jeff McErlain from Kings of Tone
Like many of the players we are discussing, Billy lets the amp work for him. He cranks it up and lets it rip, he controls his distortion levels with his volume knob. I suggest you work on this especially if you want to get the most out of your guitar. A good amp will react to your dynamics, pick attack, volume knob, and tone knob. If I plug into an amp and it doesn't clean up as I play softer, I'll try to find another amp. The amp should be an extension of your guitar. In this clip I said on Marshalls I like the bass on 10, that is true for the later "lead" circuit. The opposite is often true for the earlier "bass" circuit models such as the JTM45.
