Installed the jack yesterday, as mentioned, pickup output is low but certainly useable. Neck pickup volume pot seems to be the only one that works. No signal from the bridge pickup, and tone control has zero affect. Tone from the one working pickup is good tho', very old-school with the flatwounds. I dig it, and, I usually only use the neck pickup on two-pickup hollowbodies anyway.
New tailpiece on its way.
