I use stagepro anthem with acoustic Furch guitar and I must say the sound is nice. If I compare to it Yamaha's original miced pickups I might prefer Yamaha a bit, but in general they both sound good. Be carefull wich strings you put on, because the sound might be quite bright and crisp.
The one thing I miss is the tuner speed. It takes some time for the tuner to start working and takes few seconds more for each strings. If you're on the stage and in a hurry, you might sonsider other options. In general I'm very satisfied with the product, I use it now for at least a year with no problems.
