I'm in need of a rackmount system to handle effects. All I need really is delay, chorus, reverb, and flange (although I'm sure I'll use other things like EQ and Compression at times). I don't need a pre-amp and I don't need distortion/overdrive.

Between the G-Major and The Rocktron Xpression. which would you choose and why?
I found the G-Major to be easier to work with than the Xpression. I also much preferred the delays and reverbs of the G-Major to those of the Xpression.

Thanks for the input Kendall. How about the build quality? I've read quite a few reviews about the knobs actually falling off. Have you had an issues with that or with the unit freezing?
