P90 bridge p/up seems to “float”

    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.

    Kinmans sound great to my ears.
    I have one at the bridge position on my SG Classic and it roars.

    Face-melting hi gain without the 60 cycle hum. Why anyone would tolerate 60 cycle hum in 2020 is beyond my comprehension.

    Stock P-90 at neck for cleans and Kinman stacked humbucker under a P-90 cover at the bridge for hi gain use is my favorite pup combo.

    Yep foam is the answer.

    It sounds like your pickup is pretty high though. Can we see a photo ?

    That's pretty standard. The bridge pickups on SG standards with the full batwings and humbuckers have the issue too. Foam is always the answer. The routing for the neck and bridge pickups is the same, so the bridge pickup is always going to be further from the body. On a P-90 this means that it's farther up on the screws with longer springs. Stiffer springs can help, as can foam.

    As for noiseless pickups, they are missing something. Period. They can be great pickups with a great sound, but they miss something that a true Single Coil P-90 has.

    I'm primarily a classical musician (trombone), so yes, I can hear it.

    The only thing missing from noiseless pickups is 60 cycle hum. Period.
    No one said anything about noiseless pickups trying to sound like single coils.

    They have their own sound and are a great solution for installing stacked humbuckers in a guitar routed for single coils. No need to hack the guitar up routing the pup cavities for full-sized humbuckers.

    Eh Gasket, have you ever tried a dummy coil with a P90. I wonder if it's doable.

    Thinking back on this ... dunno where I'd put it :rofl:

    Foam is quick and easy and will prolly work for what you're trying to do, but I have been known to replace springs with hard plastic tubular spacers on that particular style of mount.

    It's a fidgety process involving math and measurements to figure the approximate length of tube to use, but it's well worth it, I believe. Rock solid.

    Just be sure not to tighten too much or you'll strip the wood.

    Just make sure it is a non-magnetic material or you could see some oddness in the low end response as some of the field of flux is (I know this word isn't really the best way to state what happens here but WYGD, eh?) 'sucked' under the pickup.

    Ingenious ... but he says it does sound different with the coil activated, à la P100. Since I don't stack OD, disto and fuzz pedals, I'll embrace my minimal hum.

    Us old guys used strips of popsicle stick to adjust P-90 height. It retains that all too important hard connection with the wood that adds girth to the tone of a P90
