How does this work for double necks?Measuring the string height on a bass and the associated adjustment are very simple. Just stand with the bass in playing position and measure with a tape measure from where the E string crosses the nut (not the bridge as some people say) to the floor. If the string height is greater than your inside leg you need to intonate your trousers. Alternatively wear shoes with higher heels when playing - this is the technique universally adopted by Glam Rock people.
If the string height is less than your inside leg the only reliable solution is to learn to play sitting down.
Or if standing on cabs?
