J-Retro with Precision and Musicman pickups

[Beedster]

I'm building an interesting fretless and am thinking about a circuit to go with the MM and P-Bass pickups (Nordy Big Splitman and NP4A respectively). I'm wondering what folk's experience has been with a J-Retro with either type of PUP, not necessarily the Nordies in partisular. I'm also interesting in whether there might be any issues using MM/P-Bass PUPs through an active circuit e.g., balance/interaction between the two?

Hi Mate

 

My alpha is not too far from your set up

 

Although its a Nordy Bigman + NP4A (reverse P) with a uni pre as opposed to the J-retro.

works a treat, off the top of my head there are gain trims for each pup, as well as giving it a good go over on pup heights etc, 

Does it work? hell yes!

Lovely, and doesn’t look a whole lot different to my project. Uni Pre is a good shout, I do like the format and function if the J-Retro 👍

Always wondered how this would sound. There plenty of MM + J combo basses out there but haven't seen this before

In a word, meaty 👍

Sounds like this!

In all seriousness though, its versatile as F#ck pardon my midlands accent

roll back on the fat MM for huge farting bridge pickup goodness, solo the P for well, that P sound, blend them together for a full fat bigger than Jazz, Jazz bass sound.

one good thing about the John east stuff is the active blend so i dont think you get that standard scoopyness, I dunno, I'm not that technical.

 

If I had a fender style bass, deffo get the J-Retro, anything else the uni stuff, think it's more of less the same, just form factor etc.

 

Just enquiring with Chris at Alpha now about my next build! wallet forgive me!

I’m a massive fan of John East’s work having J-Retro and U-Retro pre’s in most of my active basses. But, for fretless, I much prefer the simplicity of a passive circuit. My Fender Tony Franklin fretless PJ is all passive, two pickups, 3-way Strat style switch, and a single volume and tone. Best sounding fretless I have played, with mwahh for days. 

The J-Retro does have a pronounced low mid boost baked in, but I think John might have added a dip switch or jumper for a flatter response in the newer J-Retros. Mine are the older style so I have a lot of the bass controlled dialled back.

I had a J Retro Deluxe with a pair of stacked J pickups: the neck one sounded quite P like.

I did find the preamp to be a bit bass boosted / scooped when set to the mid points on the controls so if it is an option to have a flatter starting point I would go for that - especially for P tones as that really is all about the mids.

 

Not tried that preamp with a MM type.

 

The only thing in my mind is that the right settings for the MM might be quite different to those needed for the P. MM often benefits from a bit of bass boost and a bit of a scoop and that normally kills a traditional P tone.

 

If the plan is to use one or the other pickups then I don't see any downsides, but a mix of the two might be more difficult to dial in easily.

 

Sounds like a great project though.

 

When I was planning my PingRay I did think about having both P and MM but I prioritised the MM placement to match a 70s stingray and then meant the P pickup would need to be slightly closer to the neck than its usual position. So I didn't bother with the P.

 

I did think about solving the problem by using a 51 P pickup instead as that was small enough to also go in it's traditional position. But in the end I just stuck with the MM. I might do it in future though - just for fun!

I don’t know if this is relevant Chris, but I had a J-Tone once with CS Jazz pickups and it was great, but when I used it with Fralin dual-coil Jazz pickups the preamp couldn’t handle it and was popping and clicking when I dug in. I spoke to John, but he said he had no idea what the issue was 🤷🏻‍♂️
