I had an LS2 many, many years ago and I swapped a couple of the jack sockets to facilitate better/easier cable runs. Perhaps this is his solution or maybe he bought my old one
I used to do a number those in my old band. When the keyboardist originally suggested Gold, I was sceptical, but I loved playing it, still do (I play along at home).
I tend to have my strap length to match how the bass sits when I’m sitting (or thereabouts). Fortunately, it seems to be pretty much the same for all my basses, regardless of body shape.
