The humbucker has a nice warm rhythm sound with good sustain (more bass than highs, though EQ takes care of that). Not muddy at all. Very warm sound, suitable for jazz or ska if you wanted. Don't plan on playing any metal with it, though it can handle a little distortion. The condenser mic accurately produces the guitar's sound, though it tends to feed back when played too loud through my fender Princeton chorus electric amp. It sound sweet through my Fender Passport PA system. I'm guessing the Princeton feeds back more the speakers project alot more ringing highs high's than the passport, which the mic "hears" because of it's excellent frequency response. You shouldn't have any trouble running this through a PA, though I may be concerned running it through 'acoustic' amps that are optimized for piezo pickups. Using the SA-6 with a passport, I was able to crank up the mic to near room-shaking volume with the speaker 3 feet away without feedback. The passport (standard) doesn't project alot of highs. The pickup without EQ and the mic all the way up has a great solo unplugged sound for either strumming or picking. I find, though, when I need to kick up the volume and play over bass and drums, I have to back off on the mic and boost the highs on the humbucker. However, rather than do this, I mix in the piezo already installed on my guitar. Combine this thing with a piezo (with the piezo's mid's scooped out of the picture, highs boosted slightly) and now the guitar sings. Run the mixed signal through a Presonus compressor, and now it's ready for the studio. I'm playing a $300 Hohner acoustic electric with shadow electronics. The guitar has an excellent sound. It's not a Taylor, but it plays better than many $600-$1000 guitars I've played. I was looking for a pickup that would reproduce the acoustic sound, something I could plug straight into PA's of varying quality. I would take the setup I have now over any acoustic electric I've yet played under $2000. The pickup is well worth the cost, and played through a decent PA, will accurately reproduce (if I may use the industry buzzwords) the "subtle nuances" of your acoustic guitar. If you have the cash to spend, this pickup is definitely worth it. Note that the pickup outputs a mono signal into a TRS jack. I was able to run my Piezo through the ring channel on the SA6's TRS jack, so now I have a pretty versatile system.
