Finally had enough
I invested about 6 grand in a new pa ( the lead singer sold his) haul it to every gig and set it up.
lead singer, cannot adjust volume levels on his guitar, claims he cannot hear his monitor even though I am using 500 watts each into a brand new trio of MRX JBL monitors, Pushes it so far it feeds back and cliams I dont know how to mix.( I have been playing pro for 27 years) I have no trouble hearing mine nor dioes the bass player.
He is the only one who alwyas complains about something, blows up, can't hear and plays too loud.
Told them I am done. I have anew gig this weekend with the drummer and bass player as a trio
