i have been in situations where i have been booked on 3 decks, only to have a booth with really horrible monitors. just 2 weeks ago actually, they setup 3 decks and gave me one bloody monitor that had blown and was all distorted..

i could barely mix on 2 let alone 3. so of course afterwords i had people assuming i cant mix on 3 decks or just have 3 there for show etc...

when really i saved myself from a "3 deck disaster" by not using the 3rd one.

now if people want me to play on 3 i make sure that they agree to having 2 good, working monitors on each side of the decks.
