I recently had some Nordy NP4's and a bridge NJ4SE installed into my Fender Highway 1 Upgrade P bass... I'm running a stacked 250k/250k VOL/VOL pot and just one tone pot... The guy who did the install for me is called James Mumford www.mumfordguitars.com.au if you look at that page there is a flickr slideshow of my bass being routed and the J installed down the bottom of his webpage. I can't recommend James enough if you need any guitar work done (and you are in or around Melbourne), he really takes the time to get everything spot on. I got the J pickup routed into the 70's position closer to the bridge for more bite... I've yet to rehearse with these new pickups in the bass but I though I would post up a sound clip do demo how they sound and just how versatile a PJ can be! In this clip I have joined together 5 different settings (changing after each 4 bars (the last setting I stay on until the end).. so they are in order PJ tone open P tone open J tone open PJ tone half open J tone closed recorded direct to HDD through my Demeter 201S.. closing the tone half really helps clean up the fret noise, these Nordy pickups seem quite HIFI (but still with heaps of depth) so you have to keep the playing CLEAN!! All in all I'm very happy with the bass now, the J in the bridge gives it SO MUCH MORE flexibility, I can go from deep subby P thump to snappy growly J... As a side note, these Hwy1 Upgrades are just amazing, it's the evenest playing bass I've ever owned... lovely neck.. light weight.. this baby has relieved so much of my bass gas, especially now with the J growl at my fingertips! Call me a heretic but I love it way more than the Sadowsky Metro RV5 I used to own... please excuse the slightly wooden playing and backing midi file, I just figured this line out 5 min. Actually really like this line, just got to get the flow happening a bit better.. enjoy!
