Need some help here fellas(and ladies). I play through a 73svt and I really want to send that great tone to the front of house PA / monitors but as most of you know there is no DI on the early SVT heads. When I ask them to mic my cab most sound guys grab a SM58 which does not reproduce bass well at all, thats when I tell them never mind and just run direct passave through my SADI. Is there a way to run direct from the back of the svt through one of the other outs? Like 1/4 to xlr? And what effect will this have on the head (ohms and all)? Should I just invest in a good bass mic and which one is good and tough enough to play live with over and over?
