I'm thinking of buying it.I play mostly hard rock metal but i'm also a fun of blues and classic rock.
go with whatever floats your boat i've heard nothing but good things about the hardwire pedals
I don't know about the valve distortion but I have the Hardwire tube overdrive and it's awesome. From everything I've seen about the Hardwire line of pedals, you probably can't go wrong.
what amp are you using?
