Watch the Funky Child: Solo online guitar lesson by Jeff McErlain from Blues-Rock Evolution
When it comes to tone, gear only makes up about 10% of the equation. I'm not saying that 10% doesn't keep me up at night and cause me to go deep in debt, but the big secret is that good tone is actually in your hands.
Try playing with your fingers, try different picks or pick attack angles, pick harder, pick softer, pick at different parts of the neck, change pickup positions and use your tone knobs. My favorite tonal control? The volume knob.
