I'm the bassist for my church where the congregation seats about 1200 people. My rig is this: Cirrus 6string > Peavey Pro500 head > Peavey 410tvx. I send my signal out to the main board via the DI from the amp head with it being EQ'd. I use my rig mainly as my monitor, but it can still be heard aloud in the congregation. My problem is this. This weekend we had a special practice whereby another bassist came in to learn some music. He played on my rig using my bass and while it sounded great within several feet of the rig, I moved off of the platform out into the seating area. IT SUCKED! The sound was completely muddy with almost no clarity. I was blown away. I tried playing with the EQ a little but to no avail. My music minister agreed that up close it sounds awesome but away from the platform IT SUCKS! Another problem is that I am the only bassist and this other bassist coming along was for a day only so I did not get to work with the problem. Although the rig is mainly for a monitor it can still be heard during services. Mind you there was no one in the seating area the church was empty other than us on the platform. The mains were NOT on, it was simply the sound of my rig about 150 feet away. I know that there are many variables to this problem and it is hard for a simple answer, but is there one? I thought maybe a good reverb might help, Am I wrong?
