I have but I didn't like it very much. During a period of trying different pickups out, I bought the Stat-B, put it on and found it quite nice. After fitting the cork, it was pretty much plug and play. It has a nice woody tone to it.
A little later, I bought a Dyn-B and a Pre-AII. I wanted to use the Dyn-B in conjunction with the other pickup in lieu of a microphone. So far, I haven't had much luck with the Dyn-B but I haven't done the massive amount of work needed to find just the right spot for it. While I was messing around with the Dyn-B, I tried the Stat with the Pre-AII. I found that I prefer the Stat-B with the little preamp that it comes with. I worked with it for a while but never got a sound out of it that was better than the little pre that comes with the Stat.
Because the output of the Pre-AII is XLR only, I couldn't bypass the input pre or the EQ on my Focus which meant finding the right gain staging was a bit onerous and the output of the Pre-AII is EXTREMELY hot which didn't help. If it had a 1/4 inch out and I could run it through the effects return of the Focus bypassing the EQ and input preamp, it would be a lot easier to use with an amp. It seems to really be designed for running through a PA.
Long story short, the Dyn-B and Pre-AII are sitting on a shelf waiting for a day when I have time to experiment. The little pre that comes with the Stat-B is in my gig bag and actually goes to the gig.
