When I started playing bass I was convinced like many that you are supposed to rest your thumb on the pickup. I had a Warwick Corvette. I always found it hard to reach the G string. My fingers had to cover a lot of space. When I first got a Sterling I got stressed out because my first one didn't have a neck pickup and trying to play the strings between the bridge pickup and the bridge were like plucking piano strings. Someone suggested resting my thumb on the E string and moving it up when I needed to play the E string. It sounded difficult, but it took me minutes to learn and became natural very quickly. When you test your thumb on the E string you only have to stretch three strings to the G string. You have to stretch four strings when you rest on the pickup. In addition, you automatically mute the E string when you rest your thumb on it. In the past I didn't like playing a P Base because the adjusting screw was on the top of the pickup where I thought I had to rest my thumb. I ended up returning the single pickup Sterling for the Sterling HS. But I kept using a floating thumb technique. I now find it very easy to shift between basses regardless of the pickup placement. A Stingray and P Bass are no more difficult than my Sterling HS and Warwick Thumb. I highly suggest transitioning to this technique if you are currently using the pickup as a thumb rest. It makes things easier.
