How is this strung?

[Annoying Twit]

How is this bass strung? Looking at it and considering B-C to be standard for a six string, I can't guess which extra string this bass has. It looks like it might be a low F#, as there seem to be quite a few thick strings. But could someone more knowledgeable and eagle-eyed comment?

BTW: I'm not thinking of buying it, just curious.

Ask Dood

My Tsai is tuned B-F. However, the strings that were on it when it arrived were a little haphazard. I would expect off-the-shelf 7-strings to be supplied as B-F because strings bigger than .135 or so aren't exactly common. IIRC, Dood goes F#-C, and I'm sure there's at least one other BCer using a bottom string which came off a suspension bridge (wasn't someone talking of a C# bottom?).
