I have a '92 LP Custom that had the 490T. Currently using an SD Custom. Can't say I really care for either, at least in that guitar. The guitar has a "dark" tone. Honestly, never really heard much difference between these pups in this guitar. Picked up a 2015'ish Gibson Midtown last year with the Burtbuckers. These pickups, at least in this guitar, sound great. Brighter, with some guts and articulate. The Volume and Tone knobs work well with these. I toy with replacing the pups in the Custom with the Burstbuckers.
