Thanks so far for your comments and the links! I'm really trying to find the 12fret version, even if it takes a bit longer. I asked frailers.com if they have one available. Open for the 14fret version only if it's a really good deal...
Thanks everybody, I will think about changing the cone again but will definitely replace the nut and saddle. Michael, what do you mean by setting the strings flat? The break angle from saddle to tailpiece?
any experiences with upgrading the MM Blues 28 with a different cone or saddle? Was it worth it soundwise?
Since I play lap style (with a nut extender), I think it would be better to replace the original rounded saddle with one that is not rounded. Should be more comfortable to play. Since the National cones come with a saddle, I thought about getting one of those and replace both - the existing Continental cone and the saddle.
I just acquired a used MM Blues 28. I would like to play it lap style with a nut extender. Can I just add the nut extender and leave everything else as it is? Or is there anything else that needs to be adjusted?
