New Amp Shelves Day. Edsal Muscle Rack 30 x 60 x 12 shelves meant to be one unit 60" high, split into two 30" high shelves. Gets the Supro and the Tone Master up off the ground a bit closer to ear level, and consolidates some space a bit. It's actually a 5 shelf kit that I was thinking I could bridge the middle to get the stack off the ground with the 5th shelf, but I didn't fully think through how the boltless shelves would actually connect to allow that. Pretty happy for $35 though.
