"I was in the market for a studio-grade compressor pedal, and then API came out with this studio console for the pedalboard! It contains the best compressor and EQ circuits I've ever heard for guitar. This is basically two of their 500 series racks tuned for guitar for $?!? The value is incredible. And, in addition, it's an amazing direct box. It practically sounds mastered before you do anything in your DAW to the recorded track. I'm serious when I say this is the best purchase I've made in a long time, and definitely something any guitarist could use for a number of applications. I have no doubt it could be used as a great preamp for other instruments, as well!"
