The back is not included. Mounting seals for threading cable ties are attached to the back. You should be able to remove them with a spatula, metal ruler, etc., but you could also use the existing ones to bundle DC cables, etc. Also, strong pedal lock tape is attached to the upper back surface due to the effects pedals being attached there. Nothing is attached to the power supply mounting area. This board was very convenient. Above all, the ability to freely change the width of each tier is a major advantage, I think. This size is not very common these days, so I hope someone will use it. #EffecterBoard #EffecterCase #PedalBoard Compact black effecter board with adjustable slide mounts. - Type: Effecter Board - Material: Metal - Size: Compact - Color: Black - Features: Adjustable slide mounts Thank you for viewing.
