. . .my friends who around me suggest Modern5
I have owned two Sadowsky PJs and a Modern. There is a WORLD of difference between the PJ and the modern.
The modern's soapbars - and probably even more the placement of the PU - give the modern a very quick, punchy, aggressive sound. You can hear it in kosma's post, but there he has it tamed down quite a bit. It can VERY MUCH more aggressive than that. KJung describes the tone as having "space between the notes." I think that is a very accurate description.
IME, the Sadowsky PJ can sound like a P bass if you let it. In passive mode with the neck soloed, it cops a very presentable old-school P bass vibe, IMO. Maybe not as good as some other "modern" p basses, but in the context of the mix, it certainly worked for me.
The Metro version I had was the "R", and like Chef, I didn't fully connect with it. It just didn't have the cut I was looking for compared to the JJ Sadowskys. It sounded GREAT in thinner mixes, but with a lush, multi-piece lineup, it didn't do it for me.
It could have been the PUs. It could have been the woods, but I didn't keep it.
The NYC PJ I had was ash/maple. The coolest wrinkle about it was that it was a "reverse" P config. That is, the bass side PU was closer to the bridge and the treble side was forward. To my ear, this "modernized" the bass a great deal. It added a lot of articulation to the B and E and really quickened the attack. At the same time it took the edge off the higher strings and have them a little rounder bloom. IMO, it made for a better balanced bass.
It doesn't sound like it would make lot of difference, but it did to my ear. The bass was routed for either layout. I had another PG made for it and swapped the PU to the conventional layout. The difference was considerable to me.
I am SORT OF interested in finding another PJ, but I have to say that the Sadowsky HC JJ seems to be more my thing. I love the presence they have in the mix. With every Sadowsky I have had, the JJ just has more of it than the PJ has and still has all the low end you could want.
