I bought another ART Tube MP and a couple of Levelars (tube compressor) the other day. Then I got overwhelmed with all the wires running on the floor, the MP's clip light wouldn't turn to yellow or red, even though the signal was clipping, so I returned it all and I'll sell my old used Tube MP. I want to build a rack for recording. Anyway, I noticed this new product: Presonus Blue Tube mic preamp (stereo). Does anybody have experiences with it? I really like the layout - controls and inputs on the front instead of top - you can actually put this in a rack, better readouts and it's only $149 at SamAsh for 2 preamps (in one box). What do you think?
