I'm here like.. once a month maybe?
Not sure where the "focused on metal" regarding MIKKO comes from but I hear it every now and then. I always thought it was pretty well balanced with a FNDR combo, Sure 2x12, Zila 2x12, vintage british cabs etc.
Either way I personally don't believe in genre specific IR's at this point but that's kind of subjective - I think the Mega Old in Essentials will cover any genre thrown at it but because people see Mega they think metal. I definitely intend to cover more ground in future!
