Cheers for all the input.
The singer/guitarist claims to be a soundman but it's become very apparent over these last couple of gigs that he doesn't have a clue about sound - he can set up the desk but that's it!
We've had a chat about placement of gear on stage (so I'm not standing right in front of my amp and not really hearing anything, I'm gonna look at eq'ing options for on stage and going FOH (for him, our fiddle and moi) and sort something out that has a better overall balance as an on stage mix as well as out house mix. We've also agreed that he doesn't need all those feckin' guitar stands and that he can put stuff back into his car instead of leaving it on stage for the whole gig, wasting valuable room!
All your advice will be considered and used in the new stage set up!
Again thanks to all for the advice!
