So, my awesome sister-in-law gave me this for my birthday - the bass version of the then-popular Klira Triumphator (I don't know if the bass had a different name, couldn't find anything on the web).
Objectively, this is low end, even for german instruments from the 60's.
Action is pretty high for today's standards, but it makes up for it with medium scale, a tiny neck and very narrow string spacing. I have cleaned the electronics so far, adjusted the neck, and moved the bridge for (almost) correct intonation. I think I will try a neck shim, it looks like it can go lower than my Hofner 185.
It even sounds better than my Hofner. Just solid 60ies beat thumpiness, but surprisingly bright. Strings are medium scale flats, and I'm almost certain they're more than 40 years old. No need to change, they're perfectly fine.
I will definitely gig this one.
