    A violinmaking group I belong to was discussing Bridge wheels...a client of mine had given me a copy of this article when I would not install wheels in his orchestral bass after spending serious amounts of time adjusting his tone. Anyway, I mentioned the article and someone knew where it was on line, so I thought to share it with you all. It's a good read...

    Also, here are a few shots of how we install wheels in our shop:

    Oh, and if your curious...we never intalled the wheels. He has instead three bridges.

  3. The Andrew Brown article that Eric mentioned has a lot of good information in it, but as we have mentioned in some previous discussions, some of the luthiers who frequent this forum feel that it is a fatally flawed study because it makes the assumption that all instruments will behave the same way as the one instrument used in the study. My experience over the years tell me this is a false assumption. Every bass is different and what works well on one bass will not necessarily work well on another. Brass adjusters would be my last choice for most basses, but on some instruments they sound great. I would recommend starting with lighter weight adjusters for starters. Then, if you're not happy with the sound, try something a little heavier. As long as you stay with adjusters that have 1/4" x 20 tpi threads, there are adjusters available in several sizes, weights and materials for you to experiment with.
     
  4. Eric, Yeah thanks for sharing all that stuff....by the way i'd like to plug Jr Music and Eric Roy in particular. I've been dealing with these people for years and the service has always been excellent!!
     
  5. Ah, Rhode Island, where it all began for me. Would you believe I saw John Coltrane in Providence when he was playing with Earl Bostic?

    That adjuster study has been around for awhile. Ed Fuqua dispatched it quite colorfully, the message being similar to that of Bob B. It tries to reduce something that is necessarily variable and subjective to cold, fixed and quantifiable "scientific" fact. It ends up being a bit precious.
