The John East preamp club

As promised. Uni Pre really makes for a clean installation.

I put a J Retro in my '76 Jazz and love it! Sounds great and very helpful to have such control in a live setting. Only thing that I didn't like was the knobs. While they're high quality, they looked too small to my eyes so I modded Fender Deluxe knobs. Looks more at home on my bass but the top stacked knob is hard to grip with sweaty fingers. Does anyone know where to get black metal knobs like the ones that come with the East but are the size of stock Jazz knobs?

Hi ihave deluxe bass and i really like its knobs. So I wanna replace East knos with deluxe stacked knobs but they dont fit to John east shafts. So How did you mod the fender stacked knob? did you drill them? Thanks!

I had sent this in a PM a while back... Good luck!

(1) Genuine Fender 90s 00s Deluxe Black Stacked Jazz Bass Knob 004-9411-000

you will need 3. They were the lowest I found at the time. They aren't cheap but liked it much more.
I took the East knobs and just found a drill bit that was as close to the hole as possible. Dont forget to back the set screws all the way out of Fender knobs before drilling. The bottoms pretty much pressed on and the set screw didn't do much but it never slipped. The top was more touchy and best to do with a drill press if available. The part to be most careful about was the depth of the hole in top knobs. You should feel little resistance drilling it out and when you hit bottom it'll take more effort and stop right away.

Anyone know if East makes a preamp for a jazz plate that includes the mid stack? I see the new Jazz pre that is different than the J-retro, using the treble and bass from the Uni Pre, but I'm looking for essentially a uni pre on a jazz plate, if thats not a total pipe dream.

The original J-Retro has the mid stack.

the original J retro has the built in upper mid curve that the newer Uni pre and the SPM2 modules don't have. Which I dont want. Unless the J retros now have the internal jumper, allowing you to bypass the mid curve for a flat response....

Just ordered my third John East pre. I have a J-Retro in a Jazz V (currently for sale in the classifieds), a Uni-Pre 5 knob in a Lakland 55-02, and I'm having a custom bass built (see here: New Moonshine Guitars custom bass!) which will have a 4 knob UNI-Pre installed.

I've used many onboard preamps over the years, including some high end ones such as the Mike Pope Flexcore, and John's beats them all!

the report is VERY good. Having played a whole lot of onboards including some of the fanciest and most boutique ones, the Uni Pre basically smokes everything from the perspectives of design, build quality, ease of installation, reliability, tone, and tone shaping capability. They are the cats pajamas.

I think there would be a big market for a John East Preamp pedal. Use memory pots to have programability (similar to the Sansamp BDDI programmable).

Imagine having a Uni-Pre running 18v inside a pedal that you could use with every bass you own...wow!
