I'm going to sound judgemental for a moment as I can't listen to your youtube clip, so I'm giving my opinion based souly on how I percieve those settings pictured might sound.
First off, I'd recommend trying to getting the soundman to give you a recording off the board. That way you can listen back afterwards and give the mix a critical listen. Sometimes soundmen will tell you to turn down because you're too loud, but sometimes they'll tell you to turn down if your tone doesn't fit right. For instance, the settings you show have have some pretty jacked up presence settings and the soundman may be trying to counter a bright, ice picky tone.
Good idea but the drums aren't mic'd and neither is the horn so I don't think a recording would give a true comparison, but it was something I had already thought of. As far as the settings and prescence, I can understand where your coming from there too. The only problem is your gonna have to take my word on this, I play a G&L Comanche. The pickups are called Z-Coils, and they are very bassy and warm. In fact I would say they are a dark sounding pickup. So I agree the knobs say very bright but it's not as bad as you might think.
Alternatively, if the soundman can't/won't record the band from the board have someone do it out in the congregation.... far enough back that the house mix is dominant rather than the stage mix.
The camera we are using is put at the very back of the chapel.
I've found that if my tone is warm and smooth I can usually get away with more volume than if it's cutting, bright or abbrasive.
If you're listening to your cab off axis you'll tend to jack the high end to compensate for the dull/bassy sound you get when off axis. The audience and the microphone however get to listen to the full enslaught of those treble/presence frequencies that the 2x12 is blasting at your shins. If you tilt your cab up so that you can get a direct earful you'll get a better idea of what everyone else is hearing and adjust your settings accordingly.
I'm not off axis here but I understand what your saying, I'm gonna get one of these when the tax return comes. http://www.ampendage.com/ And then move further forward from the amp also.
Also, listeners tend to like some compression on guitar tones. Not neccisarily the pedal variety, but the natural tube variety. If you've ever seen people wince at a Telecaster through a Fender Twin you know what I'm talking about. I do this. Anyway, on a Mark the midrange knob tends to control how stiff or compressed the amp sounds. Lowering that knob will soften the response and may ease up on the ear of the listener. Somewhere around 9:00 is basically neutral, and turning it up from there acts sort of like boosting the amp with an overdrive pedal. Set the overall response/feel with the mid knob, then use the graphic EQ to control how much mid is present in the final product.
My exact approach. My question is this, is the middle line on the GEQ zero? Another words can you only add with the GEQ or does it cut and add depending on where you are in relation to the middle line?
