I have bought this pickup with the intention to upgrade one of my Epiphone guitars at the bridge position. The final effect is satisfying. I can now reach classic Les Paul tones with ease.
The pickup can be installed at any piece of gear that has humbucker pickup cavity. It is particularly suitable for SG and Les Paul style guitars. It's a good first upgrade for the Epiphone guitars and it looks great with the nickel cover.
The tone is quite raw and one has to carefully dial the tone pot to tame it. For more subltle playing it may be worth installing capacitors. My favourite tone position is at about 6/10. For traditional rock, one can open the tone pot entirely.
The tone is very responsive, maybe less dynamic than strat style single-coil pickups, but its suitable for mid-heavy genres. In rock mode, riffs are agressive and solos cut through the mix very well.
If you use a pair of Burstbuckers or a Burstbucker at the neck position and 57 Classic at the neck position you can get a good funk tones in the middle position. They work particularly well with the Fender-style amps (American clean).
The pickup is not for all of the genres. If you are into extremely modern high-gain genres it may prove insufficient. It has tons of classic tones inside for most other music styles. If you already have a stratocaster, telecaster and a hollow/semi-hollow instrument, a guitar with Burstbuckers would naturally complement your available tonal palette.
As for price point, it closely compares to the DiMarzio and Seymour Duncan products. I am perfectly happy with BurstBuckers and Gibson's raw properties can be valuable if properly used in the mix.
If you prefer more mellow genres, Gibson 57 Classic or SD JB may be your first choice.
