I want to put my Fender Bassman 300 into a rack setup... namely into this rack. I had to get some repairs done and the repair guy suggested it, so I decided it might be a good idea. I was thinking that I could just take off the covering and just use the screw holes to mount it. My questions are... is it possible? If it is, will I need any special stuff to put it in? And how many rack spaces will it take? Thanks.
