I'm a VOCALIST for a TRIBUTE BAND. When I first read about the BOSS VE-20 Vocal Processor, I had to check it out. I went down to Sam Ash and purchased it. I've used this product for my live performances and the reaction is incredible. For the music I'm doing, I'm bringing Studio to a live setting. What I love about the BOSS VE-20 is the double and triple track effect. Also, the harmony setting's. Any VOCALIST would be pleased once they hear the BOSS VE-20 Vocal Processor. I know, it happened to me. The BOSS VE-20 Vocal Processor , the BEST and inexpensive Vocal Processor around!!
