Here's the real deal from someone who knows this story from the very first moments it started. Yngwie didn't have a lot of input into the pickups he used previously. He was fairly young both in age and in his career when he made his previous pickup choice. At that time, his big concern was hum canceling and his old pickups were hum free.
In the case of his Seymour Duncan pickups, he was intimately involved in the development process from the very beginning. There were many revs that went back and forth and many minor tweaks. According to Yngwie, he had never been this involved in voicing his pickups. And he never knew these possibilities existed.
Not only was he was dialing in the tone, but also the feel. Put tone aside for a moment. He was very specific about the way the pickup needed to behave under his fingers. He wanted his picked notes and his hammer-ons and pull-offs to sound nearly identical. He had never before dealt with that challenge in pickup design. He has a style that he calls "legato-staccato," and it has to sound the same above and below the 12th fret. That was something he didn't have in his previous pickups, but we were able to dial it in.
And then there is the tone. He wanted something hotter than vintage Fender, but still in the Strat territory. And the neck and bridge pickups had to cover different tonal challenges. With his previous pickups, the neck and bridge were pretty much the same pickup but with a different pole piece stagger. With the YJM Furys, they have totally different magnet structures.
Finally, there was Yngwie's involvement in the process. I think most of you would be very surprised to know how "into" this process he was. During the development cycle, he and I would often talk several times a day to dial in very specific frequencies or "feel" considerations. He often told me how excited he was to be involved in this project. Once he called me to make sure that an overnight shipment was going to be at his mailbox before 10:00 that morning and he said, "Evan, you have no idea how excited I am about all this. I'm standing at the mailbox right now with a hot soldering iron in my hand." I loved that one. And yes, he did all the pickup installations and testing himself. No roadies or techs.
Was our ad copy a little arrogant? Perhaps. But to say that Yngwie's switch to Seymour Duncan was simply a matter of money is not only cynical, it's wrong.
I'll end this post with this thought. Yngwie has a reputation as a bit of a tyrant who is prone to bad behavior. I know this. And he knows it too. But that's not the Yngwie I've dealt with the last 18 months. He has always been a perfect gentleman with me and with everyone I've seen him talk with -- even at the NAMM show when he's being mobbed. He's extremely intelligent and has a strong interest in politics, literature and film. He wound pickups to raise money for Haiti. He has a loving wife and a adolescent son who appears to me to be a genius. And working with him on this project has been a pleasure and one of the highlights of my career.
I've never written this down before, but now seemed like a good time. Thanks for reading.
