I like it on warmer guitars. But on brighter guitars, i don't prefer.
So I have a Fred in two guitars, a 24 fret RG and a 22 fret JS1000. Love it in the RG - which not plugged in is a good bit brighter than the JS.
In the JS1000, the Fred that cane with it from Ibamez is thin and overly bright, most noticeable in the plain strings, but also in general just doesn't have that Fred quality to it.
