I bought a pair of Nordstrand Big Splits 5 for my Lakland 5-string last year that I installed myself, but I was disappointed with them because they were unacceptably noisy. Having three young children, I couldn't troubleshoot my install promptly and months went by. Finally, I decided to contact Nordstrand Pickups by email, and Adrian responded very promptly. I told him that I had isolated the problem to the pickups. Adrian took my word for it and told me to send back the pickups. A few days later, Adrian let me know that the pickups were diagnosed defective and he sent me a brand new pair for FREE. I installed them last night and was blown away by the beautiful tone and the SILENCE. My Lakland, equipped with the new Big Splits is now studio-ready with a tone that comes very close to my dad's all-original 1962 Fender Jazz. I'm a Nordstrand fan for life.
