thanks Tony Didn't look at it closly enough. OF COURSE its for guitar players. There goes my nice stereo sound from my keyboard so its out. Time to pull out the Harmony M again.
NO, NO, NO .... you won't loose your precious stereo mix at all. You simply plug ONE SIDE of the kb into the unit then on to your amp/mixer. Stereo image is not affected, and the vocal is mono anyway.
