In a similar fashion, I've had a Mex Jazz Deluxe for a few years now and have loved it, and indeed still do. However, of late I've had an urge to get a P. After a few false starts concerning available funds, I've taken the plunge and today took delivery of a new Squire Matt Freeman Precision, in vintage white, black pick guard and maple fretboard with tinted lacquer (looks fantastic).
My only reservation before taking the plunge was the playability of the P neck, as I'd got really used to the thin jazz neck. I'd played a few P's in stores at the back end of last year, but there's never enough stock on hand to try out back to back, and I certainly didn't find a relatively local store with stock of the Matt Freeman model..........my reservations were unfounded!
Got it home and lowered the saddles a little, and WOW! I'm so impressed, a nice low action and no fret buzz make it a pleasure to play. I use it with an Aphex Bass Exciter I bought from another BC'er and I can't understand why I waited so long before getting a P. The combination (after some dial tweaking) is fantastic, there is so much bottom end, and with clarity. I ALWAYS chose my jazz over the other basses I had, but now I really can't put this P down.
