it's been a while since I bought it, and I dedicated it a lot of time in both playing and trying strings to find the "spot on set".
talking about the overall instrument, it's well built, the truss rod reacts with small movements and it's really stable, my luthier also noticed it, and the overall weight and balance are perfect, 3.8kg and it doesn't dive.
my real problem was "the strings".
I tried many different sets and gauges I normally use, both flats and rounds
Rotosound Swing in both 45-105 and 40-100
Rotosound Jazz 45-105
Fender flats 45-100
Ernie Ball nickel 45-100 and 50-105
Fender nickel 45-105
D'Addario nickel 45-105
GHS Precision flats 45-95
Labella Deep Talking 43-104
after all this changing, considering that every set was used for a while both at home and rehearsals/studio (except the Labella, which had some problems on the D-string and the shop refunded me), I was astonished by the GHS P flats, that responded in a way that I didn't expect!
with most roundwound sets this bass sounded somewhat "dark", and with most flats it sounded less focused. the worst were the Rotosound Jazz, for example, a set of strings I loved on a Vintera 60's P bass I've had a few months ago, and I expected to sound good on this '71, but no, it sounded so hollow and confused.
I then found a set of GHS P-flats that I had in the drawer, brand new and probably bought a long time ago, maybe some Amazon offer I couldn't refuse (here in Italy they cost 50/55€), and tried them.
my first impression was astonishment. I'm used to that set of strings, and I usually like the dark and middy response, the thuddy E-string and all those typical characteristics of P-flats, but on this particular instrument they were "bright", more sparkly, with a livelier E-string, without losing the typical mid-focus that these strings are known for.

also, the tension and balance on this bass is particularly spot-on, it's like this bass was born for them, or viceversa.
after some rehearsals with them and a recording session for my punk band (the links up there), I thought that maybe I could've tried a set of Labella, so I bought a 43-104 set. the sound was "good", but nothing special, a bit muffled and dark, losing the mid presence of the GHS, and also the D string had a rattle issue and the shop refunded me, so I went back to the GHS, and now, since December 2025, they were never removed.
the sound is better focused and somehow brighter than with rounds, the notes are clearer, even after using them for a couple of months, and in live situations the bass drilled everything with ease.
I still find strange that they respond in this way on this bass, because I've also used them on a Stingray, and they deadened the sound so much that it felt like playing with pillows and blankets on the amplifier.
this '71 maintains the sustain, shows less dead spots compared to other strings, and the E string sounds good and balanced.
talking about the "mojo", I still haven't found it, ti's just a good Precision bass, with some characteristics on it's own, and that probably shows it's best with this particular set of strings.
I'm one of those players that believes that every bass has it's right strings set

in the end, this is a good Precision, and if took only as a "player", it's not worth the extra "vintage" money.
I bought it as an investment and to try a "vintage" instrument, but if I could go back in time, I'd probably won't buy it.
