I'm considering a set for my '83 57 RI Precision. Does anyone use these monsters?

Yes, I recently put them on my Epiphone, and now it sounds very much like a double bass (upright). I really like the sound!

I recently put them on my Hofner and it has never sounded better.

However, for a solid body Fender bass, I personally prefer the La Bella Deep Talkin' Flats.

But for hollow basses, the tru bass strings can't be beat.

Yeah, on my Michael Kelly fretless ABG. They sound good. Beware of the increased string gauge though, I had to adjust (read file out) my nut.

Nice strings. IME the "B" and "E" have intonation issues above the 10th fret but it may not matter, depending on your application. (Do a search and you'll see this is indeed a common problem. In my case it was pointed out again by my luthier when doing a fingerboard redress.)

I currently have a set on my fretless and just play around the rough spots.

It's my understanding that the Labella version of this string does not suffer any intonation problems at all.

I went ahead and bought 'em. After reslotting the nut and doing a complete setup I gotta say that I really like these strings.

My '57 P has a very lightweight alder body and combined with a maple neck/fingerboard, the bass has a very lively tone with a little more upper mid accentuation than I was wanting to hear. The tapewounds really tamed things down in the right way by being more low/lowmid heavy with less information present in the upper mids. This balances out the inherent response of the instrument/wood and there's still plenty of punch on tap. Cool! I think I'm keeping these on for a while- after a years worth of playing I bet they'll sound perfect.

I do love the La Bella Deep Talkin' Flats or the Sadowsky flats (also made by La Bella) on my Fender Jazz, and I did try them both on my 57 P but it wasn't the sound I was looking for.

Thanks for your input folks. Talkbass rocks!
