Each has it own. Mighty is small with more colors and gobos with separate color and gobo wheels.
The MX-1 is a little bigger but its like half the weight of the Mighty and well, its an import.
Also price, the Mighty�s MSRP is about $700, the MX-1�s MSRP is about $600. you can obviously get them for less. Guitar Center here in Vegas sells the MX-1�s for about $450.
The MX-1 is very very popular (if that tells you anything), but it is limited by its total possible combinations.
I have (2) MX-4�s and the movement is nice and clean. I have also seen Mighty�s in demo rooms and at shows and they too are pretty clean moving. And yes you can sync them up to do all sorts of pretty things
or you can have them each do different pretty things
I would have to put the Mighty slightly above the MX-1 just because of its number of gobos and colors. 19 possibilities vs. what, over 400.
But would I buy the Mighty over the MX-1, I would have to actually sit and think on that one. You basically have to decide what�s important to you.
