Wasnt sure which Forum this went it so I took a wild guess

Whats a Decent affordable gigging microphone? used for Singing/screaming

£60 max

^ not exactly under 60 GBP, but i would have to agree. very affordable vocal mic that works well for singing and screaming.

i cant think of anything that i know of that is under 60 GBP that i would consider buying. i would suggest saving up that extra bit and grabbing the sm58. or snag one used, its not like those things are known for breaking.
