It's just silly asking this here on jemsite

Ask it anywhere else and the 81 will be the clear winner.
It's better, fatter, smoother, heard on countless rock and metal records, works GREAT with Marshall and Mesa, sustains like nothing else and is simply the only choice if you are playing metal.
In fact I can get you more versatile sounds out of an 81 than out of an Evo and that's
neck Evo - the bridge Evo is so shril and rubbish that you can't even begin to compare it to an EMG.
