Hi everyone
I have a 2006 Firebird V that developed a bad sitar twang on the G and B string. I thought it might be the nut, but it was doing on fretted notes as well. I tried cleaning up the saddle slots and putting on new strings but it was still bad. I play blues and rock on fairly clean settings, so it was quite noticeable.
I'd heard about Callaham ABR-1 bridges made out of billet steel and decided to try one.
http://www.callahamguitars.com/abr1.htm The bad buzzy sitar sound is gone. The bridges are made in Virginia,USA, and sell for $130.00 USD.
The big difference was in the overall tone and sustain. I don't have a great ear, but even I can tell it's better.
It was a fairly easy job and I thought I would share this in case someone else is having the same problems.
I now see that this is more of a review and I should post it in the proper place in the forum.
