Good but...
Great sounding unit with good functions, such as XLR and SPDIF connectivity [I haven't had call to use the USB side of things]. Unfortunately the build quality seems a bit dodgy to me as mine has developed a fault on the Input knob...

Best MultiFX Rack under $500
Great, classic Lexicon Sounds. I love that this works as an AU with the USB cable so it sucks less memory when I'm running logic. Great for the Studio.

agreed, the MX300 is great, you could review it in details for everyone and people who have never tried would know what makes it so good....
