Ok, I'm kinda tired of this situation most of the times when I play live. It's something I've never experienced at rehearsals. Everytime I play live, the vocal microphone is "electrified", I guess it doesn't carry 220/110 volts because otherwise I'd pass out each time I sing my first lines...but the electric shock going through my mouth each time I touch the ball of the microphone is painful enough to bother me through the whole set. Last shows I tried not to touch the ball, but working with the distance while singing and trying to give a decent show is hard and sometimes I get a bit further making voice to fade or sound thin. I'm the lead singer and guitar player of my band. I think this situation happens when distortion is active, and I haven't noticed that electric show in between songs when I address to people. Mind that I play Metal, so distortion is running 99% of the time. Another big detail is that distortion has always come from my processor boards, being that my previous Korg AX3000G and my actual POD HD500, so it's hard for me to think of an amp head malfunction. Last show our soundman said perhaps the monitors were too close to the microphone. A friend who repairs electronic stuff said maybe the microphones used in those venues could be all broken and used, and I should bring my own microphone. Has anyone had experience with this issue? Should I bring my own SM58? Should monitors go further? Or the only hope is to buy a wireless microphone and use it everytime I play live? Thanks in advance!
