Re: Muddy Bridge
I already had an 85 in the bridge of an ESP MII (which I sold 5yrs ago). Good but I still prefer the cut of the 81 in the bridge for palm mutting. If I wanted something close to an 85 in passive, the crunch lab might do the trick, in my experience CL is less "round" than the 85 . However, I want slightly more cut than the Crunch Lab, if possible.
However you are right the 85 is an amazing PU (neck or bridge).
By the way I found my 89 (one of the first/old ones) not to sound the same as the 85 in the neck, the 85 seemed to me hotter than the 89. Maybe it's just me as they are supposed to be the same.
