I owned one of these relic'd 44-64 PJ's up until very recently. It was by far the best-playing bass I've ever owned, and it was heartbreaking to let go of it. As soon as I can afford it financially again, I plan on buying another.
The fretwork and build quality was immaculate, and the neck was hands-down the best neck I've ever played. It's smooth, fast, and incredibly stable. Since mine was a PJ, it had a jazz neck (I just don't get along with 1.75" P necks). You can just feel the labor and love put into the neck profile and playability.
Tonally, it was a PJ, nailing all 3 tones you'd expect from any Fender, Nash, etc. I had zero complaints about Lakland's in-house pickups, they gave me everything I could have wanted and expected. The only issue I ever had was that there was a little hum, so I had to shield the pickup cavities and back side of the pickguard.
As soon as I started playing it, I felt right at home. It just felt like it was meant to be in my hands, it felt broken in but not beaten, and it was inspiring and fun to play. You really won't be disappointed if you decide to buy it!
My finances are finding this to be a mighty dangerous reply ...
