Right, I'm a pro musician of 30years.
E Bass, Double Bass, Guitar.
I recently had one of my double basses needing a neck repair and picked up a new tailpiece while procrastinating about doing it.
I picked up this tailgut on a whim during a Thomann shop to go with the tailpiece.
So - a lovely little buy!
Really nice, easy to tie (look it up on line, it's an absolute doddle!)
Zero stretch, really stable.
It is also easy to adjust, which I had to do initially to get the right length I wanted.
It's not wire which I love!
This went on a 1940's Cech solid body swell back 3/4 Bass.
I'm not the type of guy to say that the sound of this bass was massively changed by this, but it's so much nicer to have this on it than a piece of steel wire!
Con's - None
I picked up a small one for a violin for a fiddle player I know and he loves his, I'll be swooping the tailgut over on my other double bass as a result.
