I guess I understand what you all mean by boomy. But was the EVO neck installed on a 22-fret or 24-fret guitar?
I've noticed the position (also the wood of course, smaller impact tough) really changes the bass EQ of a pickup. I remember having tested a long time ago a JS1000 with a paf pro in it: I found it too boomy, but I bought many years later a paf pro which was in a 24-fret RG and I founded it too thin. The EVO neck for me is great because even the low notes are percussive enough and this is what I was searching for.
