Howdy everyone

Yesterday, I picked up a very good deal on what I believe to be a pretty decent upright bass. The label on the inside says "Wilhelm Kohl copy of Antonius Stradivarius".

The bass was played previously by a jazz player, so the adjustable bridge is at it's lowest setting.

What should I do to set this bass up for bluegrass? I know I should raise the bridge height, but how much, and what is the proper way to do so?

The bass sounds amazing now, so I don't want to mess anything up.
Any help you could offer for a newbie upright player would be greatly appreciated
thanks!

I have been trying to find the particular maker of my upright, Wilhelm Kohl (or thats what the label says, at least), but I can't find anything. Does anyone know anything about this maker?
thanks again!

If it sounds and plays good like it is, I would not touch a thing. The previous owner may have had it professionally set-up and it is as good as it can sound now. Maybe take some measurements and notes so that if something changes you can put bridge/string height/soundpost back in the same set-up/condition. Once you play it awhile, you’ll learn where you’d like to tweak this or that.
