Most important to know - I have not installed them in a guitar yet. I do a lot of guitar work and work with lots of pickup types and brands so the review is based on first impressions and visual inspection. The pickup is well built - aside from the cheaper, thinner rubber coated wiring, everything else looks quality. The wiring is not a surprise based on the cost - and not a big deal. They come nicely packaged with everything you need to mount the pickup in a pickguard. The edges are smooth and clean and the rails sit nicely in the casing. With cheaper pickups, many times, the rails sit wonky in the plastic, the pickup is covered in wax, or the edges are rough - I have encountered the issues individually and cumulatively in past budget pickups I have worked with - that is not the case with this pickup. Vey nicely made. As I stated, I have not installed the pickup, but I did test it with a multi-meter and it does give a signal. My reading didnt match the description reading exactly, but its very close and thats common - regardless - this is a hot pickup. I expect that it will give a high output, bright sound based on the meter reading and its makeup so no concerns on if I will like it. Its a good pickup, especially for the price. I got another one through Vine and I will be purchasing a third to build out my next project. I recommend this for a noiseless, humbucker sound upgrade to your single-coil guitar.
