I always used a wired sm58. For me it was always the most dependable for my live performance's. As a Lead Vocalist I needed to evolved into the world of wireless which would give me freedom on stage and off. I found it with the sure wireless. Over the years I have tried many other systems. For the money the sure BLX24R/SM58 delivers GREAT vocal sound. No doubt I am very pleased. Thanks zZounds for your play as you pay option. Vini D Lead Vocalist for BANDIT
