Greetings, All!

I had a recent brainstorm regarding my next parts-bass project. I'm casting out to the "collective-y'all" for input and ideas (both general and specific), especially since I'm thinking of traveling into waters quite unknown to me.

I recently picked up an Arctic White Mighty Mite Jazz body. My first thought was to make a straight-up J/J out of it. I already have a set of Fender Super 55's ready to go and they'd most-likely sound great with Link Removed. But a curious though struck me the other day…what if I were to do an H/H Music Man-style configuration, along with a 5-way switch and preamp? How cool could that be?!

I did some searches for something similar, but the search parameters are too common and yield a bazillion results. I saw some references to "JazzRays", but they were mostly passing references with little hard data. However, I rather like the nickname, so that's kinda stuck with me.

Like I said before, this is unknown territory for me. I've never owned any kind of Music Man instrument, let alone delved into the finer points of it's pickups and electronics suite. That, and the only active bass I've ever owned didn't last long for me. (It wasn't the EQ's fault…it was a five-stringer, which didn't work out for me) So, I'm turning my brainstorm over to the good people on this forum to get whatever input I can. So armed, I'll ultimately decide if it's worth pursuing or if it should remain as "just a thought".

If I were to pursue this idea, here's a few things I definitely want or are amenable to;
  1. Pickups & Electronics: Two pickups are a "must-have". I've grown rather fond of having that extra flexibility/versatility. I've also been looking at a rotary-style, 5-way switch in one Jazz control plate's pre-existing holes. (Volume/Rotary/2-band EQ perhaps?) Since I'm mostly accustomed to the simplicity of passive controls, I'm leaning towards a 2-band EQ…something nice and simple, but effective, to try out first.
  2. Neck: Whatever direction I go with the electronics, I'm definitely going with some sort of Jazz neck. I'm seriously considering something from USACG…probably a 7.25" to 9.5" compound radius.
  3. Hardware: I already have a Fender American Standard bridge, so no discussion is needed on that front. However, I doubt I'll be drilling out the body to make it string-through. I'll probably have to hit up Terrapin, or someone similar, for a custom pickguard. (For the record, no tort. It'll be gloss black to contrast the white body.)
  4. Routing: Obviously some extra routing would be necessary. If I have to have a side-mounted jack installed, or a little more taken out under the guard for a preamp/battery/additional knobs or switches, that would be fine.
On the subject of #4; One side-benefit I discovered during my previous project was that I could always switch the neck pickup back to the originally-intended Jazz pup. Just swap out the pickguard and pickup, do a little rewiring…et violá!

One last thing, the "sordid topic of coin"…cost. I have no intention of going "bat-poop crazy" on electronics. I want something that will achieve something close to, if not spot-on, the classic Music Man sound, but without breaking the bank. If that means having to plunder the guts of a S.U.B. Ray and shoe-horn a second pickup into it or something like that, so be it. Obviously, I'll be keeping an eye on the TB Classifieds for bits and pieces, but if someone has first-hand, or even second-hand, knowledge of something that'll get the job done and not cost more than the neck, body and hardware combined, that would be awesome.

So now that I've established some parameters, I leave the rest to the "collective-y'all" for discussion and suggestions. If there's something I haven't considered, an omission/error, or a thread I missed that could help, feel free to hit me up with as many questions and references as necessary. I hope to learn a great deal during this project, much like I did during my previous one.

Many thanks in advance!

There is a while thread on mm pickups in the pickups and electronics forum. I think the Nordstrands are supposed to be closest to the pre Ernie Ball pickups, but they are pretty expensive. The basses I've played with Bartolini pickups all seemed much less aggressive than the real deal. The preamp strikes me as trickier. I haven't seen anything that was consistently described as close to the real deal
 
lol.....I was thinking of doing a single coil for the neck and a Stingray style for the bridge... but hey maybe and HH would be killer... with coil taps?

I haven't ruled out something similar. I still have those Super 55's (split-coil…no hum), which are rather mighty. Perhaps J/MM with a 3-way ON/ON/ON switch in lieu of a blend knob?

If I can't find something satisfactory that's local, I may consider importing a Invalid Link Removed, but only if it can be adapted to a dual-pickup configuration.
 
Lakland's signature setup is MM/J and it is quite a popular combination.

A BigMan with a Big Single would be a variant you could consider if you want a beefy sound...

That's a pretty serious configuration there, Doner. How is this system similar and/or different from a dual-humbucker Music Man's? Also, how does the Lakland's "beefiness" compare to a P/J in series (which I already have that in my last project)?
 
Hey Malak......Did you ever try the Modern Player Jazz when it was still around?

I got to sample one of the first generation MP-J's when they first came out. It looked and felt good, but the sound seemed "just kinda 'there'", if that makes any sense. It is possible that it could've used a little tweak to the off-the-rack setup. Maybe bringing the pickups a little higher might've given it more "oomph"? I haven't had a chance to try a second gen.

Looks-wise, my finished product will likely appear quite similar to them, at a glance.
 
Doner got me thinking and I suppose a small clarification might be in order…

I already have a few P/J's and a couple J/J's, each with their own little twist on their themes, in the way each bass sounds a bit different, even when identically wired. This time around, I'd like to try getting something that lands more in the Tony Levin/Music Man ballpark. (emphasis on "ballpark"…I'm not trying to cop "this sound" from "that song/album") It's a sonic landscape I have yet to explore.

Plus, as I said earlier, I don't want to do yet another Fender J/J or P/J variant build. I love 'em, but I want to try something along the design-specs of another iconic system…in this case, a Music Man-style setup. Certainly, there might be some variations from the classic theme, like using a rotary switch instead of a lever for the coil selection. At this point, I'm ruling very little out. However…

I'm gonna head-off any suggestion that I just buy a Music Man bass. I've stated in other threads that "Feel" and "Looks" are very important criteria to me, with "Sound" coming in third. I don't have a serious problem with MM's looks, but the Fender Jazz esthetic and ergonomics are my preference (my hands and eyes already know what they like). Besides, I already have the body…let's get creative with what we've got! :D
 
The retrovibe "stinger" preamp is just a copy of the 2 band mm preamp (which it sounds like you want). If you're willing to spend the money, then I agree with the general consensus that the Nordstrand mm4.2 is an amazing pickup, but with the preamp, anything similar should sound close.

On a side note, I recommend wiring your pickups with series parallel/switches, as you get two noticeably different, but very usable tones.

But definitely go for it, the "stingray conversion" turned my decrepit first bass into my joint number 1 player
 
I have a friend whose main bass is an 80s MIJ P Bass. When he got it, it had a G & L humbucker installed in the bridge position. He said it sounded great, but it over powered the stock pickup; it sounded like crap. He replaced it with a Duncan Quarter Pounder. Then it sounded great.
The QP had enough output to balance the humbucker, so they sounded good together, and when he used just the P pickup, he didn't have to contend with a significant volume drop. The tone of the two pickups was huge.
I'm not sure what kind of front pickup you want to use, but I just thought I'd throw that out there. I like the suggestion about using a Nordstrand big single.
(btw, another friend of mine has ordered a Nordstrand big single, that he is going to put in his single pu Jaguar bass. I'm looking forward to hearing it when he's done. It will be mounted in the MM 'sweet spot')
