I ordered the Orange Combo Cover 2x12 for my Orange Crush CR120C. The cover fits exactly on this amp. On both sides are cavitys. So you can reach the carrying handles of the amp without removing the cover.
I decided for the Orange Combo Cover because my Orange Crush CR120C amp is standing in the rehearsal room of my Hard Rock band and I just wanted a protection for my amp and I am really confident that this cover will save my amp from dust, beer and ash. Perhaps the cavities build a little security hole but I think the use is greater than the risk. ;)
