In a short time of owning a Sadowsky M5, I quickly learned to love the Sadowsky preamp, more than any other that I've used. It offers great tone possibility, in a way that is foreign to bassists that embrace 3-band(+) preamps. Some Sadowsky preamp revelations for me.
1. Boost-only EQ, FET preamp. Sadowsky prefers FET to op-amp circuits. He doesn't favor subtractive-EQ tone in FET circuits, disliking the tonal effect.
2. 2 bands only, bass (40hz) and treble (4khz)
3. Wide Q for both, or as Sadowsky explains in his club thread, a "wide bell curve"
4. Passive tone control removes highs
5. Boosting treble EQ activates the wide bell curve centered at 4khz, reaching into high mids
6. Rolling off passive tone control yields attenuation of highs, leaving boosted high mids
7. Meanwhile, in this context, boosting bass activates the wide bell curve centered at 40hz, reaching low mids
8. In this manner, a 2-band preamp becomes a 3-band (boosted high and low mids) in conjunction with the passive tone control
9. Finally, using an HPF removes lows you don't want, leaving desired bass and low mids
Maybe these steps seem cumbersome. In use they are extremely simple with awesome and repeatable result. The formula? Add a bit of bass and treble. Then, roll off a bit of passive tone control. Fine tune according to your ear. So easy.
Some might argue to use a related Aguilar OPB1. However, the Sadowsky 2-band preamp has proprietary added circuitry and potentiometers. One can purchase the entire setup prewired aftermarket, keeping it simple.
When I build my next Roscoe, I will be sending a 2-band prewired Sadowsky preamp to KR for inclusion on the bass. I guess I'll be the first in this thread to have done so? However, I encourage @ragetoca to beat me to the punch.

I think that the best sounding active jazz bass I have owned was a Sadowsky with the passive tone. I wish I had that one back. It was Seafoam green with a white pearl guard and rosewood board. Looked great and played and sounded amazing. That and a Rob Allen Mouse 30 are about the only 2 basses over all these years that I wish I had back.
So I have this crazy idea....since I own both a Roscoe SKB 5 string and a Sadowsky Metro 5 string I am willing to try to swap the preamp on these basses as a test and see what kind of results/tone/sound I would get.....I can always put them back, right?
Crazy idea sounds like great idea. The main challenge might be getting pots to fit in holes and cavities. Are pots long enough to fit through varying top depths, and right diameters? Are cavities deep enough for all modules?
A thing I find interesting is that I never hear any Sadowsky users, or Sadowsky Club thread members swapping out their Sadowsky preamps for anything else.
So, it's not only potentially interesting to hear about a Sadowsky preamp in a Roscoe, it's equally interesting to hear about a 3-band Bart preamp in a Sadowsky. Sounds like a grand experiment for both basses.
And, of course you can swap those preamps back, but maybe you won't want to.

Well, Roscoe-verse, it's time to shed a tear -- who in their right mind would drill a hole in the back of a perfectly fine SKB3006??

Total shame!
Those holes would certainly be deal breakers for me. Sounds like it really should get a new nut too.
At least the seller is honest and not trying to hide the defects until delivery to a buyer.
Personally, though, I think someone should confiscate his drill and files.

Ouch. While not the end of the world, someone had too much free time on their hands.
After sliding back into the passive four string love nest again I feel a purge coming on lol. I’m not saying I won’t sell off my Roscoe’s again…. But I’ll never sell them ALL off again. Somethings never change.

The more things change the more they stay the same!
Fortunately, the passive 4 string I love is a Roscoe and a gift so it's staying. I still have my Koa Century 5 that, even though I'm not playing much at this time, I don't see going anywhere anytime soon. The Fender P5 and the G&L JB-2 (another gift) round out the stable. I may start bringing 3 basses to gigs but we'll see if it'd be worth the hassle. My son likes to play the G&L so there's always that.After sliding back into the passive four string love nest again I feel a purge coming on lol. I’m not saying I won’t sell off my Roscoe’s again….

Will be on the lookout in the classifieds.
That being said; I was at a party the other day and the bass player had a USA Lakland 44-64 through an Aggie Rig (AG700 and 12s) no pedals. And it was the sweetest tone I've ever heard.
The AG700 paired with 1 or 2 SL12 cabinets is a great sounding rig!
