That's one he built from scratch.
That's Uwe, not me. Big difference between a short and long scale E, but I've never really done any comparisons with 32" vs. 34" scale. There's got to be a difference, I don't know how significant it might be.
Yeah, blame the kraut when he's not around! I hate it when after two comparatively minor transgressions in 1914 and 1939 we always end up as SSscapegoatSS.
A 32" E - in my irrelevant book - doesn't have the ferocity of a 34", but there are three other strings to play on/with and E strings are overrated anyway, it's the place to catch your breath after you have run out of ideas.
Besides, the E of an X-Factor is not really medium scale, it is is Rickenbakerish semi-long scale (mind you: the E of a Ric is not a Fender or Gibson long scale E either) in its extended D mode.
Why anybody would call a Kubicki "no treble" is beyond me, you can klänk wiff dat zzzing like hell (unless you go into that ultra low bass reggae mode it offers), it's hugely respnsive and attack-happy bass, that multi-ply neck is not just fast to play, but also fast in transmitting tone (though a bit dead/clinical too)!
Kubickis are cool whether the classic X-Factor or the one I have (34" Factor), so was John Taylor's haircut btw!
