I'm starting to look into buying a rack unit to hold my stuff. Right now, though, all I have is a head that would take up 2 rack spaces, and a wireless which is 1/2 size with the antennas on the back. I also have a pedal tuner, though I'm looking into buying a rackmount tuner as well. Here are my questions: 1) How would one go about rackmounting a 1/2 size unit (i.e. half the width of the rack)? 2) One thing I like about the pedal tuner is that it mutes everything when I tune my bass. Can I do this with a rackmount tuner?
