This pickups are cheaper then other signature EMG pickups, however I was surprised of sound quality. Easy to install as this kit is solderless. However this kit is designed for Les Paul (single cut) guitars with toggle switch (toggle switch is not included). If you need for superstrat with lever type position switch I would recommend additionally order EMG 3-way switch B165. So, to make this wiring fully solderless. Wiring instruction I found on EMG official website for 3-way switch B165 for 2 active pickups, 1 tone and 1 volume. And keep in mind this pickups provided without frames and jack without jack plate. I ordered all this items additionally. Ever if your guitar was with passive pickups before, as mine, it is still enough place to put the battery inside. You can attach battery to the inner wall with doble tape, you will find tape on the power bus in the kit. Generally I'm fully satisfied with result. It was easy to connect all parts. Now I really enjoy my guitar with new voice. Now I start think to change pickups on my other guitars ))).
