Not sure if this is the best place to post this, but I am going to be playing live again soon and will need to mic my 1x12 combo. I don't have any experience with mic's and also don't have a lot of cash to lay out for one. I've been researching budget mic's and came across two that may be decent for the job: the Nady SPC-25 and the Digital Reference DR-GX1. They are in the $35 - $40 price range. Anyone have any experience with these (or others <$50) in a live setting? Or am I wasting my time with these (should I look for a used SM57 - 58)? Thanks!
