This cover is made by Orange for their Tiny Terror combo amp. It is made of thin canvas like material and has the Orange logo embroidered on it.
This cover will fit the TT15C12 Tiny Terror Combo Amp.
Orange changed this cover so that this amp, which has the handle on the side, is carried with the handle on the top.
After removing the cover, it must be rotated to position for the handle to be on the side, and controls on top, but when carrying it with the cover on, the handle is on the top and the large opening is on the bottom.
