I've just recently started playing with a fairly large pedal board. This weekend I played my first big show through a large PA with the board. Luckily we had an awesome sound guy who has been to some of our practices and knows what we like to sound like and we had a long sound check hours before the show. My setup is bass>pedal board(good amount of filters and dirt)>Mark bass little MarkII>Mark Bass 4x10. They mic'ed the cab and ran a DI from my head. The sound through the monitors was really trebly and tinny and when I used effects or overdrive it got really distorted and farty. We spent quite a while trying to figure it out and really couldn't get it too much better. I was able to walk off stage while I played a bit and it sounded much better through the mains and everyone assured me after the show that my tone sounded awesome. But on stage I just had to keep telling myself that it sounded good out there cause it just sounded like farting to me. The whole show got professionally recorded so once I get that I guess I'll know how I really sounded. I've had problems before with my DI on the mark bass sounding tinny but not the farty sound I got this time. Any suggestions on what I could tell the sound guy on the next show? We should have the same sound guy which is great because he really takes time getting the sound right and doing what we ask but this was his first time doing sound for a bass that has so many effects. So what would you all recommend?
