Well, I've spent way too much time intonating one of my guitars (has a VSVG trem . ..PITA). I'm using a Strobostomp and getting pretty different results depending on were I put the pickups during the process. I know the singles have magnetic pull. If intonation is really a function of matching distances then I understand removing pickups pull as a possible source of distortion, but if when the pickups are up the strobe says I need different saddle positions . . .then the distance thing falls apart. Wisdom from luthiers please.
