Yamaha MX20/6

pretty basic

the board itself is clean with nice headroom but...

I've only had it for 2 months, so far so good??

I purchased this board mainly because it has 4 buses which really come in handy for recording since I have a multitrack soundcard. I would give it a high 8-ish rating in regards to recording. However,
when it comes to live sound I would give it a 3 at best. perhaps it would be more suitable for a small band in a small venue.
The beginning of my woes is hooking up stage monitors. there are no assigned sends for monitors. it does have 2 aux sends per channel which can serve as monitor outputs, but other than your ears there is no way to tell if it is clipping, no LED's. With that in mind let's talk about the built in effects, or maybe not, it comes with 16 effects which you can only use 1 at a time and they are all primarily for vocals which isn't so bad but.. you really have to crank the perimeter to notice any change in the sound, definately no "absolutely not enough headroom". the solution external effects but bare in mind it has only one effects send so unless you have a multi-channel effects processor your pretty limited. you could use the aux sends and returns for more than one effects processor but then you have no monitors, unless you want to run monitors via the group buses which once again you would have "very little" control on individual channels.
I'm in a five peice band and I run sound for another band using this board for both. I've got an awesome sound out of the fronts but monitoring the stage volume is a complete nightmare compared to some of the older boards (my old 16 channel peavey comes to mind), that have 2 monitor outputs with right and left faders and LED's for each side not to mention 2 effect sends and returns. If I could do it over again I would go with a 24ch 4 bus mackie.
This is still a pretty nice board for the money, but very limited as far as effects and monitoring.
