1 norm van maastricht 2 years ago I had snagged this years ago and thought I'd lost it. "... Pickup Balance “To balance your pickups, plug your guitar into something with level meters, such as a 4-track recorder. Play each string individually, and adjust the pickup height until the level of each string hits the same point on the meters. Typically, you’ll have to lower the bass side of the pickup. If your guitar’s overall output is quieter than what you had, simply turn up your amp to compensate. The benefit here is string-to-string clarity.” —Dave Wronski..." Shouldn't be too hard to find a usable 'level meter' online. I've not tried this but it makes a certain amount of sense.
