I use the following equip:
PA and Speakers: Yamaha EMX 860 Stereo Powered Mixer, 8 channels, 600 watts of audio power, 2-200 watts stereo for mains and 200 watts for monitors, bridgeable main channels for mono 600 watts, Separate 7 band EQ for both. Effects send and return, AUX in/out, Tape in/Record out. 2 Yamaha SM121V-600 watt cabinets used from monitors or mains 1-12 and horn in each.
Mic is an audio technica pro-3L.
Cables are pretty generic.
When i go direct with my acoustic i use a LR Baggs DI Box.
The PA has simple high/mid/low controls on each channel and a 7 band EQ. I found that the sound was very bassy/boomy sounding. I am by all means no expert on soundchecking. Also, at this point i am not using monitors. I really just use this now as a one man set up to sing through, but there may be more applications with multiple vocalists and instruments in the future.
I think i want the fx on the vocals only. If i am running guitars into the PA by mic'ing the amps then i want the amp reverb and nothing layered on top i think. For my acoustic with DI, I havent really put any verb on that, do most people???
As you can see i have more questions than answers. Who would have thought building a guitar rig would be easier than this.
