I asked the question as I contacted MD - Musical Distributors which I assume is Bothners as the HQ is the same address. First reply I got sorry the Cub12R has been discontinued. I then checked Laney.co.uk and it was still listed as a product. So I emailed MD/Bothners suddenly the story changed from no they aren't discontinued but we have brought in any Cub12R in while.
This kind of thing is reason I hate dealing with local retailers, just be up front. Had they told me truth from the start I would probably have place one on order as I am not in a particular rush.
Guess an international retailer will do.
