Dude I love me an 81.
I put it in my #1, for reasons. It’s not super articulate, it’s not a variable for volume changes but it’s consistent.
It’s a gain level I love and it’s really easy to work with. It’s not picky, it sounds mostly alike thru all amps/cabs, and it’s just super easy to play.
Can’t stand most of the Fishmans, and the older DiMarzios/Duncans I have while awesome, require much different settings to achieve the same results.
I’m not going to take those pickups out of those guitars as that’s part of the reason I bought them, but the 81 is in my main guitar for all those reasons.
They just make playing easier and more productive for me in the end.
