Most likely this has been covered here and elsewhere, and I have searched, but I am looking for a quick and up-to-date answer, so I´d appreciate any help. I am mulling over the idea of switching the P90s on my SG to humbuckers. What are the latest "non-invasive" options? No routing, only simple soldering please. I would be very grateful for brands, models, and even links if possible. Thanks in advance!
