Did gigs this past week without my normal cab (Xitone MBritt). Because of a significant amount of travel, I just backlined a FRFR cab and was provided a Yamaha (not sure of the model).
The band uses floor wedges, not ear monitors. Well, I immediately noticed that I could not hear myself even at ridiculous volumes. Needless to say, I was bummed. After the first night, I remembered that there was a separate EQ for the different outputs. I used the Monitor Output EQ and added Middle +3, Treble +1 and Presence +0.5.
BIG difference!
It wasn't my "dream tone", but it worked well. Oh, and I considered how I was sitting the mix at FOH; the engineer said it was great out front.
So there you go, FWIW.
