It was around 1986 or 7. I wanted more variety of sound/tone out of the bass. These were the days when it was my only bass and I couldn't afford/justify spending money on a second bass. Besides, as you said - it was my bass so if that's what I wanted - that's what I did. Seymour Duncan made a pu targeted at the Thunderbird called a Hawk-Bucker. The Music store in KC (Quigley's) had one so I thought - perfect. I think it was $65 which was a lot of money to me. "Vintage worth" wasn't such a big deal then, at least not like now - probably more for Fender basses. I was an adjunct professor at the Kansas City Art Institute and the wood-shop student assistant, who played guitar mentioned "are you sure you want to do this?" I said - yah, let's do it. I never routed anything before so he helped. I had studied pictures of IV's and positioned it in the same location as an original. I sent a letter to Seymour Duncan on how to wire it and he sent a hand written letter back! Never regretted doing it as it gave me all I wanted & more. And yah.., as recently talked about here - to the grave.
