Mbox Pro 3 - No Gain or Volume Control
 

Just got the new mbox 3 pro. Reset everything to default in the I/O settings. I can hear my guitar, but I can not control the gain or volume--moving the knobs does absolutely nothing. Anyone else seeing a similar issue?

Found out what i was doing wrong with the volume knob--forgot that there was a headphone volume knob. However, still having problems with the gain.

So, as any new user to such an interface, I made a mistake in thinking that I could plug my guitar into a "Line In." I found out that the "line in's" do not have built in pre-amps; thus, I would need to run the signal through an amp before plugging my guitar/bass/etc. into such a port.

In conclusion, I needed to plug into one of the front XLR combo jacks--they have the built in pre-amps necessary for my situation.
