Its a great mic. Very useful on guitar cabinets, recently nudging its way past my 25 year old SM57 UnidyneIII's
which have never failed to get 'that sound' for electric guitars. The HM1 is darker but not as grainy so placement will be an important part of your engineering skills. It can take a good number of dbs so hurting it is not an issue....however, having a pad inline or one at the input is a wise choice.
The moneyback guarantee with a very resonable trial timeline makes this mic, without a doubt, one of the best bargains in this business.
