So tonight Joan Jett and Billy Idol are playing, but we also had some local cover bands. Both bands were pretty okay, just playing hard rock covers.
First band comes in. Kemper. Guitar is buried in the mix and the little I could hear was really fizzy. But I gave it the benefit of the doubt, maybe the soundguy sucks.
Second band brought this:

Same soundguy, stage etc and holy shit, the sound improvement was night and day!!! Like the 2 bands were in different planets.
Now, some say the audience can't tell the difference. Maybe they can't tell why, but during the first band show, people were staying away from the harshness coming from the stage. Second band has a much warmer sound and more people were actually watching and engaging with the band, perhaps because they don't feel like they're being attacked by mosquitoes.
Bottom line, if you're in a band that needs any amount of guitar heaviness, just don't do modeling. Pop band, wedding, corporate? Fine. But if you play hard rock or heavier, just don't do it.
Funny thing is both guitar players were actually decent but holy cow what difference the gear makes.
