I have always used SM57 and vintage variants like 545, 548 etc, but today I'm comparing SM57 to the Beta 57A and I was completely blown away by the Beta!! Itmakes the guitar sound extremely punchy and tight, almost like Slash's tone. I'm using a 2008 Gibson Les Paul R9 through a 2019 Marshall Studio Vintage SV20H and a 1971 Marshall 1960B cab.
