Ok, so the day's festivities have come to a close and I got a chance to plug in the CLR and flip the switch.
Set-up was super easy: My Kemper rigs are all at 12:00 for rig volume, so I set the Kemper Master Volume at 4.0 as the max signal strength per the CLR instructions.
I then strummed while raising the input volume knobs on the CLR and then backed off when the clipping light came on. For me that's 1:00 on Input #1 and 2:00 on Input #2. I'm using two XLR cables.
Then I set CLR Master Volume so that the top of the white line on the knob is even with the bottom of the second dot. I then backed down my Kemper Master Volume to 1.7, which is plenty loud for apartment dweller practice. This way if I want it louder (or lower) I can adjust the Kemper Master Volume instead of having to do it on the CLR.
After all of this I quickly confirmed what I expected: this beast has the accuracy of studio monitors with the juice of an amp and an incredible horizontal range.
I compared the sound to studio monitors a buddy loaned me and the response is exact. Exact! But of course with the CLR you don't need to keep your head still.
If you are on the fence about getting one, and it's a flat studio monitor type response you want with some BOOM, and I mean BOOM, then this thing is what you need. I'm running it at the very low end of it's volume potential, but a quick turn of the unit's Master Volume knob revealed this thing is capable of blasting the paint off the walls if that's what you're after.
Worth absolutely every penny and I owe everyone on here a big thank-you for talking this thing up because the hype is 100% justified, and more.
