Plastic pickup covers too large to fit Squier P bass pickguard.
Non magnetic pole pieces don't magnetize enough per instructions creating very weak magnetic field and output.
Remaining materials are good quality.

Having read the writings of the previous reviewers I was a bit nervous at first, but there was nothing wrong with this kit.
The holes are nicely cut for the size of the magnets, so they fit snugly.
The holes on the cover line up with the holes on the flatwork.
The .710 magnets are a bit long for vintage specs? I didn`t mind. In fact I was able to use thicker wire, still ending up with more definition and detail in sound than I can get with a shorter magnet. My customer was over the moon with his fretless bass I fitted it on! And that`s what really matters, innit? Thank you guys at Stewmac for the great kit!

The first problem i've got with a stew mac winding kit. The holes are oversized and magnets are to long (shoould be 0,531 but they are 0,710) -- hope this won't happen again

This is my first kit with a problem. the magnet adjusted well in the bottom but the top fiber passed through, I had to glue it. Also the plastic cover was undersized, after a little sand, fit well.

has all the parts you need, and is very affordable..and like always, the best quality around

The bobbin top and bottom do not line up. The supplied cover doesn't fit. Neither does a Fender cover. Other than that,they are nicely made.

This is the first problem I have had with any pickup kit.

Easy to assemble, the instructions are easy to follow too. The issues I have are the height of the magnets not being vintage spec, the polepiece spacing being off, and the plastic covers that come with the kit don't even fit the pickups...
