Has anyone ever tried one of these?
I'm trying to get a full electronic upgrade kit for my Les Paul Studio.
They're about $50-80.

So far I know RSguitarworks, WCR pickups, guitar-mod sells them, I'm not sure which one would be best suited for me.

If anyone has bought one of these full upgrade kits and installed them on their guitar, please give me some insights as to how much difference you noticed, where you bought them and if you think it's worth it.
