On my Strat, next to the volume knob there is a screw on the pickguard. This is my reference point for adjusting the knob for volume. For example if i want the volume on 5 I turn the knob until the 5 is lined up with the screw.
On my Gibson, there are no such reference points. I just visually keep the tone knob at say 7 by keeping the number 7 pointing at 2 O'clock. Due to the sensistivity of the pots, this isn't accurate enough for me.(I know that sounds picky- but hey we are all picky about somethings)
With these knob pointers, you can dial the tone or volume in to more consistent and precise settings- say 5 and 1/4.
Everyone plays different. Obviously alot of folks just turn everything way up to 11, and work down from there.
I don't have any effects or "boards" or computers. I only have the 4 knobs on my SG. I always keep the knobs on my amp the same. Neutral. So I do like turning them for different effects. I know- it's lame.

Plus, I don't play out or anything, so I never need shit turned up to turbo power.
I like these little pointers. I can't wait to put them on. Just a little poor mans upgrade for me.
I was wondering what I have to do to put them on?
