No its not snug mate its quite a gap on mine, I did the same to my Stagg and its fine. If I took it down to two business cards it should be fine then do you think, that would still leave plenty of nut for someone to do it properly later if need be.
The rest of the bass is brilliant, none of this finish looks ok from 100 yards stuff, the ply rear looks really nice almost a shame to hide it and all the seams are neat with no glue or lumpy varnish etc. The company are faultless so far, the best I have ever had dealings with!
