I've mounted on my BC Rich and now I've split my humbuckers.
Soldered it myself, everything went well, no complaints about the electrical part.
The knob feels just ever so slightly flimsy...when I rotate it it doesn't have the same "drag" of the other pot, feels lighter and easier to rotate.
Also the spring for the push-pull is rather easy to engage and disengage (maybe if you pull it don't bang on the guitar :'D) but other than that it does the job.
