I have just purchased a 2020 Gibson SG Special in vintage sparkling burgundy. I love the guitar but the bridge p/up concerns me. It is loaded via two adjustable screws and appears spring loaded for adjustment. My worry is that the pickup seems pretty insecure, I can literally move the pickup by hand backwards and forwards from its setting (around 1/4” away from the strings) to a further 3/8” back toward the pickguard without any effort. The springs provide little resistance and if the guitar is played with enthusiasm the pickup can be dislodged from where it should be. The neck pickup is fine and seems far more secure. My question is - Is this normal, are bridge soap bar P90’s intended to “float” or should they feel as robust as any other pickup? Thanks.
