I bought this as a replacement for the stock pickups on a Mexican Telecaster. Don't get me wrong, the ceramic mexican pickups are fine, but they can be a little harsh and undefined at times.
The twang king neck seems more defined and clear than the stock pickup, but is still reasonably warm sounding. Note separation is good.
Build quality is great, the cover is nice and shiny and all the wiring looks sturdy. The pickup also comes with an earth wire for the cover preinstalled which is a great help for the series wiring mod...however, be careful as this third wire is quite flimsy and can easily be damaged during install. Go easy with the soldering iron!
All in, a good price for a fantastic pickup. Certainly well worth upgrading from the stock pickups.
