Well the drowning out of the vocals and loudness of the guitarist were the only problems the last serious band I was in had live. You could always here the vox and the melody, but never the lyrics. And people have mentioned that the guitar was too loud. Basically every show. This is a new band I'm in so I have no clue what to expect in terms of live sound for us. Almost every show we've played hasn't had PA support, which is why I feel like the move to stacked 210s would benefit me more so. And I just think my speaker setup was really getting the job done. My sound meshed perfectly with the guitar/drums, I just wasn't happy with my tone.
And sorry to kind of hijack this thread by the way lol
