I wanted an acoustic simulator to complement my pedalboard, because for prog rock, I also needed that tone and if possible without changing guitars.. Well, this simulator won't replace an acoustic guitar. Of course, I suspected that, but I had hoped for better. The box is not easy to adjust to find a somewhat credible setting, and on top of that, you have to carefully control your attack because it quickly produces an unpleasant background noise which is quite surprising, the result being better with the single-coil pickups of my guitars, fortunately my humbuckers, whether on my Les Paul or Schecter, can be switched to single-coil. So to conclude, it simulates, but you shouldn't expect magic! I think only electric guitars equipped with a piezo pickup can produce something convincing.. I'm going to keep it, but I'm not impressed at all by the effectiveness. Too bad, it is well presented and compact..
