No I haven't, I am content with leaving it the way it is right now.
Comparing the two guitars, the JB bridge on the ESP is very close to the RR bridge on my Epi LP. But, the SH-1 isn't even close in comparison to the SM on my Epi. The SM is just so much sweeter and cleaner. The SH-1 muddies up a bit, more undefined on the bass strings.
:D
