Michael from TITANOVATION is sending me a few pair of these adjusters, so that I can show them to luthiers and bassists. He is also going to send me a bridge with them cut in as a sample of how they work. I will have these in the next few weeks and if any luthiers are interested in checking them out, write me an email and I will send them out as interest and availability dictates. their web site is http://www.titanovation.com I am a bassist not a luthier and my interest is curiosity and the well fare of my instrument, and also an interest in innovations that make sense. ( I have no affiliation with the company) It would be great to have some of the trusted luthiers on this page take a look at these adjusters and offer their opinions.
