I read somewhere that Bartolini actually make a pickup to fit the mute cavity on a 4001/3, not sure if it's still in production though.jwr2 wrote:yep ... you have to remove the mute and remove the plastic cover on the jazz pickup and trim the jazz pickup down in size a little and it fits in ... I wire it into the same volume control and the neck pickup ... then when you flip the toggle up you get the neck pickup and jazz mute pickup at the same time ... it sounds a little like a 4005 ... if you run all 3 pickups at 10 it pretty much cancels the hum ... you can also wire it so it is always on and it bypasses the volume control or put another toggle to turn it on and off ... with just the bridge high gain and the mute jazz together you get an aggressive biting sound ... and this mod is 100% reversable ...

Interesting topic - I've had unendurable hum at the same place where the SAME rig was fine 4 weeks earlier. Now, it is my 4001, which basically is out of service with a fried output jack (that I've been meaning to fix now for forever! 
)...maybe that night the output jack reached it's end?
No...I still used that bass regularly for another few months. I did at least a bunch of rehearsals, probably another gig or two, before I got the Laredo. Oh yeah, I recorded an album with the 4001 after that "hum job" gig. It did fine at the studio, although the cabinet was in another room down the hall.
(got the Laredo a couple days after that recording session...)
Jeff R. - nice joke!
I would suppose that using a good PU for the J Bass pickup mod is a requesite. The ****** ones that came in my J bass I would put in frankenstien project...but nothing I really cared about. That's why they're not in my J bass anymore...
Also - the no bite humbucker comment: I guess I can understand it conceptually - series wiring is more direct. But I'm not sure about it, at least with my experience. Several friends and musicians I play with think I get the best bite out of my J Bass - a fretless with hi-tension flats on it, modded with Seymour Duncan stacked humbuckers. Of the 3 basses I have, by far the 4001 has the most incredible bite - with those Fender flats it could still cut through the mix like a machete - but the Laredo doesn't lack bite, it just has a far better low end. When I put the stacked humbuckers in the J I was "warned" that I'd lose the "vintage tone". I don't think I lost anything, except problems (buzz, microphonics)...I gained a lot more output juice (so the J is now comprable to the Laredo), but to me the tone stayed exactly like it was.
