I brought home my big boy today! It is a Kohr K 52Q (Czeck hybrid made by Strunal). It has great sound and a good set-up. It gets louder and louder! I think it is going to take me a week or two to get used to it after my Engelhardt. (My bowing had just gotten passable. Now I feel like I am starting over again!). I played the Kohr K65 (Chinese bass). It was easy to play and had bright sound on top two strings, lost some sound on the bottom two. But it did not get louder and louder. Thanks for all the things I learned surfing and searching the double bass forum! My photo was too "big" to fit as an attachment. Any Hints?
