In a ½ inch wooden box 11” deep 19 & 1/8 high & 14 &5/8 wide, I was able to squeeze in the Digitech VR, Behringer Composer pro XL, & a Mackie DFX-6 (with one side panel removed). For me, It’s a great quick set up unit, the power cords & signal chords for the SD1 & my Fender 1270P monitor store in the back of this unit. It also houses the VR petal & cord. I can also use my Sennheiser MD 421 regular mike or a Crown headset mike. I just pull out one power cord in the back of the box to power up everything –except my powered speakers.
