This is driving me crazy. I'd love to hear and Eon One in person. Two diiferent sources have told me its not really for keyboards or DJ's. Theres a mid frequency scoop in the middle done on purpose for the acoustic guitar singers which is what it was designed for. I'm still interested in the convienence of the all in one package and the prices are starting to come down a bit so having two for stereo is reachable.
What does your brother play thru it and where does he play ?
