Up for sale is a very high quality cab cover made for epifani. It has the Epifani logo on it, but I am not sure the maker. This cover will definitely fit the UL115. According the epifani website: UL115: Dimensions: 21.5" H x 23 " W x 17.75 " D UL310: Dimensions: 23" H x 21.5" W x 16.5 " D The depth on the 310 is actually 17.5" and the website is wrong. They did this to give that cab more depth but never updated the website. This has been discussed on TB. Of course, you could just measure yours. Anyways, as you can see it is NOT a perfect fit for the UL310. I thought it was. Its in good condition with no rips, tears or obvious signs of wear. I think these go for $80 + new. Buy mine for $45 + shipping Money order only. Only trade I would consider is for the same quality of cab cover for my UL112.
