Unfortunately it is a time thing, I had someone lined up, something else came through so I went for it, they backed out and the first guy ended up buying a bass this morning.. everything was about to work well LOLI saw that! At that price I'm shocked it hasn't been snapped up. You could easily ask for more if you aren't in a time crunch.
Well, after 30 years, I finally have one again

I'm going on vacation this coming week, and will post when I get back. But this one will be on the block soon, if anyone is interested
Okay, more important discoveries. With any active bass I almost always set the EQs to the middle (flat) and then adjust as needed, and the Kubucki was no exception. I’ve been basically only using position 2 (mid boost) with the bass boosted half way center and treble cut half way from center.
I’ve been mostly happy with the tone, but the preamp didn’t behave the way I thought it should. Passive modes were MUCH quieter than active, to the point of being basically unusable without serious changes to my amp levels. Plus it always had a bit of a weird “pushed” kind of sound, as if I had a compressor on, or was running out of headroom or something. Very hard to describe. And position 3 was SUPER scooped sounding with massive amounts of bass, which was also a completely unusual tone for me.
Well upon reading that the EQ was BOOST ONLY I decided to turn them all the way down and start there. Holy moly, what an improvement! I’m now using position 3 and just very slightly boosting treble or bass as needed, but mostly leaving them at 0. No wonder the active modes were so much louder and pushed sounding. I was running it with the bass boosted 3/4 of the way up all the time!
I’m much happier with the tones available in the bass now. It was always good sounding, but now it’s excellent sounding.
I only bought this bass because it was such a good deal, fully expecting to sell it once I got it back up and running again. And despite never being happy with an active bass and always preferring more traditional designs, it’s become my number one player. The playability and ergonomics are just so dialed in and tone is incredibly consistent throughout the whole range of the bass.
Anyone else buy one thinking it was just kind of cool, and then it became your number one?

I’d also love to know this info!Has anyone ever measured Kubicki pickups coil resistance or used magnetic paper to see the coil aperture? Does anyone know what kind of magnets are inside Kubicki pickups?
Nice! I wonder when the change over from '85 to early '86 happened. This one is dated 4/86 and has the newer control cover. I had seen some '86s with the old cover, but don't recall the date stamp. The earliest ones had a different cover, jack, preamp, and pickups, but you couldn't tell it from the front.Just up on ebay. I played a salmon Ex-Factor in around '94 here in SF at Real Guitars. I would have bought it (under $1k) but I had just bought a black '86 ($750) at Black Market Music (long gone) and so I passed.

As happens, the early days tend to be a time of day-to-day development. I think my '86 was 6/86. I can't recall if mine had the printed bridge-plate or not. It's too bad someone did such a hack-job of touching up the paint, but it can be sanded off and re-buffed to gloss. Factor finishes were very thick so there's plenty of finish to work with.Nice!

No, here's the text. Hope it posts. I cant remember the context and I'm not ready to bug Carla about it yet. I'd rather bug you guys.Does your text-only copy show who made the original post?
I found this (using Google):Does anyone recall a posting detailing cap and resistor modifications to the 18v preamp? This new Talkbass format is nearly impossible to search for things buried in the thread. I copied it to text in July of 2023 but would like to read it in the forum to determine the context for which the modifications apply.
Thanks in advance!
