I have bought this for my Orang AD30HTC head. The LxW dimensions are just fine, so is the handle hole but there is not enough length to cover all the head... it misses 3 or 4cm. It barely covers the knobs panel... not so good for preventing dust to go there.
Also, even if I am fan of Orange amps, I don't really need to have a big bold logo "screaming" it in my room (or on stage)... it is a bit naff, I think.
Fabric and overall quality are fine.
