I just picked up the Zoom RFX-2000 rack effects unit... how cool it is! I also bought a MIDI floorboard controller so I can control my vocal effects on stage myself... It works awesome! Right when I need a Halford-like scream I can select an over the top delay and get like 10 seconds of sustain.. On the fly with my foot! Sorry, I've got a woody over this and just wanted to share my enthusiasm ....
