Kubicki X Factor on SBL

I picked up a Kubicki back when they were fairly common and gave it about a half hour test drive. I loved the sonic possibilities but couldn’t get next to the headless thing. It ultimately came down to needing to order strings any time I might need some that took it off my list of basses I wanted to try.
It was around that time I also tried a Fender Jazz plus with lace sensors and Kubicki peamp. I’ve still got the J Plus and even though I struggle to play it because of age related hand issues, it remains my favorite sounding bass ever.

Kubicki's use regular strings. The ball goes at the headstock, and the other end wraps around the large tuning cog. No special strings needed.
 
Only the 4-string Ex Factor. They no longer make the full-scale Factor nor any 5-strings.

If you really wanted a 34" factor I'm pretty sure they could make you one - they're all custom built so if they have any unfinished neck blanks they can make you one. It's the same bass, but without the extender, and the two mini-frets are extended to full width. You can retro-fit a factor neck to an existing body, and in fact I knew someone back in the day who bought a second neck and swapped them over. It's probably possible (though you'd be crazy to do it!) to have a skilled builder convert an ex-factor neck to factor.

But why bother... if you want a Kubicki then you want an ex-factor.

5 stings never existed as real Factors (other than two prototypes). There are a very small number of 5 string key factors, which have the same design but with regular tuning pegs. Only around 200 were ever made, and I'm not sure if that's 4 and 5's combined. They key factors were introduced in the mid 90's by which time Kubicki's were out of fashion, so sales were limited.

Not sure I'd agree with that... The fiver seemed to me like a decent compromise of the (Ex-)Factor's ergonomics to fit five strings. A headless five would have been even nicer but I can get that committing to a five string version of their tuning bridge would require a whole lot more sales than Kubicki could reasonably expect.

(edit: On thinking about it, the tuning bridge shifts the picking and fretting areas pretty far to the left. Not that big a deal on 32" scale, but probably an issue on 34". Maybe it was better the way it was.)

yes. that's EXACTLY what the key 5 is. The key 5's are lovely basses. Play great. If you need a 5 and want a Kubicki then they are the compromise that has to be made. Though I am suppressed that Phil released them, as he didn't do compromise.


I more meant that giving up the extender, to get a 34" scale length was a strange choice. Why get a rare custom bass with a unique feature ( the extender) and then ask them to take it off so that your new bass is more like a regular bass!
