Mackie Control works great. However, there are build quality issues in recent versions. I had the original Mackie Control for about 5 years, and it was solid. Maybe one record button wore out.
Then I went to Mackie Control Universal Pro with two extenders. The scribble-strip LCD's faded to darkness within six months. I had them replaced, and those also faded to black in less than a year. I'm in touch with Mackie recently: the newest batch of LCD's should be better.
It's be best bang-for-buck controller. I just hope quality control over there in China has gotten better. (He says, knowingly, wink wink, say no more.)
I just had my MCU Pro replaced for a dim scribble strip. It was out of the Mackie Warranty (1 year) but still in the Sweetwater 2 year warranty. They just sent me another one (brand new) and I sent the original back. I notice that the scribble strip on the new unit is brighter than the one on my original ever was, even when new. Thank you Sweetwater for honoring your warranty.
Time will tell how long before this one starts to dim, if at all.
From what I have been told, the part is about $100.00 from Mackie but it is an absolute nightmare to install as literally the entire unit has to be taken apart. It looks like it would be simple, but it's not. This comes from people who have done it.
YMMV...
