One thing I would really like to see on the active CLR's is a volume control on the front (like a guitar amp usually has). That way you could adjust the volume of the monitor while playing, without affecting the FOH send from the Axe. It is pretty hard to do this while playing if you need to reach around to the back and adjust it (and keep playing).
Why not just turn the output of your amp/monitor almost full and control the overall level with the output knobs on the front of the Axe? I have a Verve 12ma and it has a spot on the volume knob that is unity gain, or about 85% of full wide open. I leave it there and then adjust my overall volume by using Out1 knob on the front of the Axe.
