I knew I would absolutely hate the Mono case. So after ordering my Luke 4 Anniversary SteamRoller, I ordered 2 used but in excellent condition Musicman SKB cases online. (I found a near mint Luke sized case for sale a few days after I ordered the first one, which was a JP model case. FYI the luke 4 acutally fits inside the JP case, albiet more snuggly than the luke case).
I just knew I'd hate the Mono case.
Turns out, I actually prefer the MONO case to the SKB cases for my purposes. Even after ordering the 2 Musicman skb cases, which are now just sitting in my closet. lol
I will say however that my MONO case does seem to have an oder inside of it, an odor similar to model adhesive or model glue. I'm assuming its the smell from the inner padding or padding adhesive. I tried airing it out for a few days under a fan, but its ever present. No big deal, just my experience.
