I bought this cover for the Fishman Loudbox Artist. Even the name suggests, that it is made for Fishman Loudbox 100, it fits the Fishman Loudbox Artist perfectly (probably, they are of the same size). There are two layers of fabric, the stitching are sturdy, and the edges are reinforced. In general slip cover looks well made. It would be nice that there is outside pocket for power cord, but really, It's not a big issue.
What I really like is the velcroed flap that opens , and makes amp handle access possible, even the cover is on.
I find it a bit expensive for what it is, but I believe it was worth it to protect the excellent amp.
Good product, I would buy it again.
