First word which comes to mind is "quality", both sound and construction. Installed in a Tele Custom, using a Wilkinson bridge w/brass saddles. Ordered with Alnico 3 magnets. Great string separation, responds to pick attack and cleans up by rolling back the volume pot an eighth or quarter turn. It took a couple of days playing to really appreciate the sound, it's the Telecaster bridge sound you always wanted, but didn't know it.
I can not live with out these tele bridge pick ups. The perfect balance of sparkle and sweet bottom end. It's just bigger sounding. It can twang or rock depending on how you hit the strings. Outstanding pick up. Dave Dills The Magpies blues band.
Great sound definitely will buy again here is a link to a guitar I built using the pickup in the neck position https://youtu.be/o2fwdrMBzbk
