This is a wonderful pickup that will bring you back in time 50 or so years, perfect fit for a vintage instrument or to retrofit a modern one with the vintage vibe. They are pretty flexible but of course, if you're style is some kind of hard core metal you may not like this sound. I own a set for bridge and neck to enhance an Highway 1 Jazz Bass, the bass has good action and good wood, the stock pickups are decent, but always lucked a bit of clarity, and right after installing those pickup it felt like I had access to a very expensive vintage instrument. The pickups have great mid presence and will roll off very nicely with the tone control, giving a great range of musicality, they also take overdrive very well. With those pickups, I strongly recommend the series/parallel mod to access an additional sound palette. The pickups are hand made and impressively aged one by one, and come with a very nice box and a cloth sack, with best compliments from Mr. Duncan himself. If you're in that mid '60 tone, you can't go wrong.
