Re: Pickup height
One of my favorite topics! And one where you get a lot of sucky advice...Like this: "I like to raise the pickup as high as it can go, then adjust the action to that; it may result in high action, but I like that." I'm glad it works for you...how-I don't know and why I can't explain.
DO THIS FIRST:
1. All poles equal height
2. Hold strings down at last fret on high and low E strings
3. Set neck to 3/32, bridge to 1/16 (Gibson factory specs)
4. Adjust the middle four pole peices to match the arc/radious of the strings
THEN
5. Play guitar and adjust individual poles for any unusually loud/quiet strings
6. Switch between bridge/neck pup and make any adjustments for volume preference. Adjusting the neck is usually the better choice.
FINALLY
7. Tweek the pups up or down equally or slightly higher/lower on one side to preference. Use SMALL adjustments. Make them both ways and pay attention to the tone & sustain as you raise and lower the pups. A small change makes a big difference
Bottom line is that pup height is a trade off of tone vs volume: And sustain is a victim if you go too far either way! It really doesn't take much of a change to really effect the tone/sustain/volume. Once you get the basic setup (both e strings), then adjust the pole pieces to match the arc/radius of the strings. Then, make very slight adjustments to each side to taste. But really, a half turn of the screw will really make a difference!
As high as possible gets the most bang for the buck in volume, but it will kill sustain. The field in a humbucker can really shut down string vibration. And too far loses signal. If you back it off just a bit I bet you'll find you sound a lot better. Crunchy tone is way more about amp settings and playing technique. If all you want is crunch set the EQ to 4/10/10 gain 7, and output 9. If you want tone, set the pups up right! Another milimeter closer to the strings won't do a thing for volume with any decent amp at those settings. And if your all about volume, don't worry if your tone sucks. Just don't blame the Duncans!
