I had a set in my fretless J bass. These pickups have bumped-up lower midrange and subdued highs making them somewhat dark and "beefy" sounding. Probably great for a meat & potatoes sound on a fretted instrument but I found the neck PU to be too dark for good fretless usage. The fretless really benefits from clarity in the upper midrange region which this neck pickup suppresses. The bridge PU works well though, because of the naturally sound of the bass at that position is less lows and more mids & highs.
Build quality is great on these. I loved the adjustable pole pieces. The pickups were very quiet and gave good output levels. They are a bit tall so fitting them into the standard depth pickup route might be tricky. My routes were 3/4" deep (iirc) and they just fit with only a minimal amount of foam under them.
I eventually swapped Area Js into my fretless and it sounded better.
