I have lately been considering an attenuator, but do not want to spend 6 or 8 hundred. I don't need bedroom levels per se, just a little knock down for stage. How does the hot plate compare to the Dr.Z Air Brake? I played an Air Brake in the store yesterday, but it's hard to tell on another rig. Has anyone tried both? Is there one I'm over looking? What's the best attenuator under $400? What about the Dr. Z Brake Lite? Thanks.
