I am obsessed with Yamaha keyboard. I own a Yamaha p80, but I broke the keys off of it too regularly from playing it really hard on tour. For Slingshot Dakota, I play a Yamaha CP 33 Keyboard through an Ibinez Tubescreamer, a Boss Bass overdrive pedal and a delay pedal. I run these to a Morely AB switch, which goes to 3 amps. The distorted keyboard sounds come out of 3 Roland amps: 2 KC550 amps and a Roland Subwoofer.
