Hi I am a vocalist in quite a successful function rock/pop band. Typical set up really. Drummer (a loud one - aren't they all?!), bass, electric guitar, and keyboards (the keyboard player swaps on to a 2nd electric guitar occasionally. I play acoustic. Like I have seen so many times in my research, I am like the majority and use an SM58 for voacl. I am looking at upgrading and spending around £150 (if need be) as a) I'd like a better mic for clarity and tone and b) to reduce feedback problems and other on stage noise. Maybe I have done too much research but I have narrowed it down to 4 and I'm just confusing myself! The 4 are.... 1) AUDIX OM-7 2) SENNHEISER E 945 3) ELECTRO-VOICE N/D767a 4) ELECTRO-VOICE N/D967 I have like a Springsteen/Joe Cocker type of voice if that helps. Any advice would be appreciated.
