JC: FWIW, I'm finding the T4 VH2 a big step up from T2/T3. I'm getting great sounding clean, clear, and distinct backup harmonies and at/approaching the sound quality I'm getting from my dedicated TC Helicon Voiceworks unit. The key (at least for me) is utilizing a decent quality 'high signal output' mic and optimally setting up the T4's mic gain/vol settings . My audiences are impressed and notice the difference. I'm currently using a Sennheiser e935. That said, I'm of course interested in hearinng George's opinion on the T4 VH2 as well. - Scott
