And that is the big problem with some sound guys: they don't have any clue about music.
And it's also the same big problem with guitar players/musicians.. they don't have a clue about sound. There's a huge difference between what is obtainable in a studio/recording situation versus live. That's why many bands sound different live vs. memorex!
Knowing what you "want" your guitar to sound like and having it sit in the "mix" are
*often* TWO different animals. Many players do not know how to achieve that having tweaked their tone at home. For example - recall Pete Thorn's original Axe-II demo vids ?? ... many thought it sounded high-ended, edgy and harsh. But I guarantee you they sit perfectly in a mix when keys, drums, bass, vocals and other instruments are added.
Great guitar tone does not come from someone soloing alone and tweaking in a bedroom thru studio monitors or phones. There's many other factors involved - such as the FM effect. How many posts on "my presets don't sound good live" have we seen here??? What you hear on your favorite recordings is often highly processed, overdubbed, multi-tracked and "squashed" into the end result. Too often folks assume that imitating that sound will work live 'cus it's on CD!! For example - kick drums sometimes have FOUR mics put on them in the studio to capture the in-the-room sound, the close-up, the direct, etc. and are then all merged together. There's no way you are going to get four mics on a kick drum for the average live venue. Same scenario with guitar...
True, there are "loser" sound guys out there for sure.. I've worked with some that shouldn't be in charge of parking, never mind a 48-channel mixing console. But it's a symbiotic relationship. If you approach the sound guy up front - not 2 minutes before you go on - and let them know your objectives, most
*WILL WORK* with you. All bets are off if you feed them garbage, right? Don't also forget that you have a PA to amplify the sound of the band. If the house PA is any good, having a cranked 4x12 on stage is NOT HELPING! If the drummer is TOO LOUD for a club venue, either turn him down or find another drummer. Lower stage volumes provide FOH with FAR greater control over your end result. That result is generally better when you and the soundguy are NOT competing.
Obviously, YMMV !
