It came today, for $949 shipped. It's mint and sounds terrific. I was ready to pay $699 for just the head and look for a suitable cabinet, so I got the both for $250 more. Can anyone better explain to me how the tube gain and pre volume knobs work in conjunction with each other? I have read numerous posts but find myself a little confused. My bass is a Schecter Studio 5-string with active EMGs, even with the tube level at 10, the LED is barely lighting. Do most folks still leave the pre volume up high and use the master as an overall volume level, or are there sweet spots to be had between the two? FWIW, I also use an Acoustic Image Focus IIR as a head to power a rack guitar rig, the Shuttle 6.0 sounds terrific for that as well, so it will serve as a backup on guitar gigs.
