I had the opportunity see Christian McBride with the Ray Brown Tribute last night. He was using a Realist Sound Clip into a GK MBE. Christian was phenomenal, but I'm not enamored with the sound of that pickup. I was close enough to the stage to actually hear it coming from the amp. In that setting it emphasizes the mid range in a very ugly way. Just my opinion though.
