I got this set of stainless steel frets on my last order as a practice set but Man oh Man was I surprised.
They are a bit wider than a Fusion III neck, I doubt that they would work for a 7-stringer but I will measure.
First thing I did was test them against the Blacksmith stainless frets and they are definetly up to par.
I will add more details in regards to the hardiness of the steel once I'll install,level, crown and polish them, as I Heard they'd be hard on tools.
All in all a quality product for the price of a set of strings.
