I was looking for a compact yet powerful acoustic amplifier. The Schertler Jam 200 isn't the lightest option (26 lbs), but it's sound quality coupled with the abundant features makes it the best one I've researched. It's has more than enough power to fill a small worship hall. The multiple channels offer great flexibility; it's basically a top notch acoustic amp with it's own PA system. I use it for classical guitar and also electric. The acoustic amp characteristics make it great for amp modeling (for the electric). If need more power, then you're probably playing somewhere with a house PA; the Jam has a direct out to cover that (then you have your own stage monitor!). Definitely recommend this amp!!!
I play mostly Santa Cruz guitars with K&K Pure Mini P/U installed. The Schertler Jam is the best sounding amp I've played. The richness of the lows through the mids (love the parametric mids) into the highs, it achieves what I most wanted, to sound like my guitar, only louder. I tried my Larrivee PV-09 with a Highlander P/U and also my old Taylor 514ce with the old Fishman blender. All sounded perfect with very little EQ adjustment. After acoustic transparency, the ability to adapt automatically to the impedance of the p/u was one of the reasons I liked this amplifier. And, if the great sound wasn't enough, it comes in a very classy looking package. I highly recommend the Schertler Jam amplifier to those who want a pure acoustic amplifier with little hassle. Amazing amp.
