Here's my Kubicki Ex Factor 4 (1994) which I purchased for 1,560,000 KRW (approx. 1,400 USD) a couple of days ago. (I live in South Korea.)
Its overall condition was excellent, except for the VERY noisy pickup blend control. A few bursts of DeoxIT into the pots got rid of the noise completely though. It's a fun-and-easy-to-play 32" scale bass with many interesting features. I guess I'll need a little time to get comfortable with this 'scale-extender' type D-tuner, since I am more used to 'tension-lowering' Hipshot Xtenders and dropped D fretboard mapping.
Thanks to its headless design, there's no neck dive at all - but the maple body and the bridge, which is a huge chunk of metal indeed, cause the opposite of neck dive only when I try to play it sitting. When I play standing up, the balance is just perfect.
The 6-position rotary switch is a bit overwhelming but I do find the normal passive position sounds very good to my ears.
