TC Helicon rackmounts
 

I am wondering if any vocalists out there have tried/used any TC Helicon vocal processors in live stage application. We are a power trio and I am only vocalist so I am looking to duplicate our studio recording sound on stage. I use many dual-sometimes triple lead vocal harmonies so I need a smart system I can preprogram and step through in live performance/. I know that Sting used TC Helicon rackmounts for the last POLICE tour so he could sing w/ himself etc...
