The best service. You can talk or email a human being who wants to set it right not prove you are wrong. The courage to provide a good product. The knowledge to provide a good product and to keep innovating. Just returned from a practice with two wind players and a percussionist. My iAMP 800 and Cxl112 (left one at home) respond to every nuance of my playing. It can sound really torqued at low levels yet is capable of clean clear huge volume. Together they sound so like what I am playing that you would think the amp is capable of one sound. As I change it changes. I use it flat and occasionally with a preset. Thanks to everyone at EA for being there!
