Ok, this cover has one job to do, thats to cover a Vox AC30 or a Vox AC15C2. The dimensions are 100% correct, however the left and right handle holes do not match up correctly, this is a bad mistake from Rockbag, how hard is it to get the measurements 100%?
Also, the cover could be 2cm longer to ensure it covers the whole Amp. If you need a dustcover for your Vox I would recommend it, but only for home use. The material is heavy duty and waterproof.
If you need to transport your Vox Amp to and from gigs/practice I highly recommend you get a hard case for it. This cover is only for home use.
Maybe Thomann could make their own version of this cover? Thomann covers are first class.
