How do I ask this question?.................On bass guitars, pickups are usually mounted loosely with screws, sponge foam or wire springs so that they can be adjusted for height, right? When we pinch the pickup with our fingers, it can be wiggled quite easily. What would be the sonic effect if the bass pickups could be solidly mounted into the body of the bass? I mean like wrenched down solid and tight? The reason why I ask is because with turntable tone arms and needles/cartridges (which is also a pickup), they are recommended to be extremely tightly bolted down to the tone arm for THE BEST PERFORMANCE! This is an audiophile fact! Wouldn't a bolted down rock solid bass guitar pickup also work best? Would love to hear some expert comments!
