Sorry to resurrect such an old thread, but I too am looking for recommendations for DB Luthiers in Scotland.
I finally managed to replace my old cheapo stentor 1950 blonde bass, which was stolen along with our van in Rome last October

We took a peek in the Violin shop in Glasgow last month and ended up leaving with a beautiful Zeller bass.
I'm loving everything about it right now. but from reading these forums one thing is re-iterated time and time again:
"get a set-up for your new bass "
Can anyone point me in the right direction?
Also this is my first post in the DB forums, hi there! I've been lurking on this site for a while now
gleaning a whole host of useful info! thanks TBers!
Thanks in advance.
Ian.
