I know this is discussed in several other threads, but I need some detailed info. I am currently using a Tube Works active box, and we have always had issues. Every other week my sound guy will ask me "what I did different?" and I always say nothing. He then says he asked because he was getting a real strong or weak signal. I was thinking about a countryman DI only because everytime I play at an important gig, and the one time I played on TV they always used a countryman. I would like any suggestions you all can give me.
