I need some advice. I play for my church and I'm having problems with good sound. We have a fairly old church building and the sanctuary was not designed with acoustics in mind. I have been playing through an Eden WT-300 head and an Ampeg B series 4x10 cab. The head is nice but the cab stinks. I turn the gain up as high as I can without clipping, and crank up the volumn but still get people telling me they can't hear me through the mix (Piano, guitar, drums, and 8 singers). Yesterday I took my little Ampeg b-50R and played through it and it seemed louder than the 4x10. Some people told me they could hear me much better. Whats up with that?
