I bought this Yamaha MG06 primarily to use for monitoring purposes for my drum set up when playing live. My monitor mix goes into the mixer along with click track from my Roland SPD-SX. I then go out to IEM'S via a hard wired Fischer belt pack. Does a great job and the features are amazing for such a small mixer.
It's well built, set out easily and feels like a good quality product.
Due to its size it's easily portable as well which is a big factor for me.
Yamaha make great products and I can't find fault with this so far, recommend.
