I have a 16.5 inch viola, and I would like to change my bridge. I found 46mm, 48mm and 50mm space.
How to choose viola bridge?
I measure the minimum distance between the f-holes..or the original bridge!
Infortunately, I have only to buy online, no violin luthier in my country!
I think even if you find the "right size", it will be tricky to someone like you or me to fit the bridge to the top plate and adjust it to the correct string height etc. etc.
I tried a local luthier to lower my bridge, but he cutted it too much lower. So I need a higher one now to correct that.
The width of the bridge at the feet should be no more than the smallest distance between the f-holes. The smallest distance is usually between the f-hole eyes closest to the neck.
The width of the bridge must be related to the position of the bassbar, the width between the eyes of F holes is only an approximate reference (not wider than, it is a good rule but with violas it may be too inaccurate).
