In that particaular case, I operate exactly the same way. I do use track eq for “musicality”. I prefer to only use the Schoeps on guitars, but in some difficult situations, I add a little bit of Di to have a more defined midbass, when the mics tend to become too “thin”. I try to delay the DI track but it’s quite uncertain method because of the guitarists movements… Always have a bit of phase coherency issues, that’s why I try to avoid Di most of the time. The mixbusses for guitars allow me only to do surgical eq with graphic eqs, to “fight against” feedback problems and resonnances which can occur in some venues. I also add a little bit of compression for one of the 3 guitarists who don’t manage dynamic as well as the others, just to control some peaks.
Maybe next show I’ll try the matrix out back to a stereo track to add a little dynamic eq on the guitar bus. The GypsieJazz guitars are very “rich” in 200Hz and 400hz, and I need to keep this on individual instruments because it’s a part of the “signature” of their sound. But sometimes the 3 guitars goes rythmic together, the 200 and 400 bump is really exagerated and I need to control it.
