Having a look through eBay (not specifically for uglies; just trawling) and a couple came up.

Want to know what the proposed new runway at Heathrow aiport will look like? Check out this 15-string bass guitar:

or the same seller’s 12-string guitar, 6-string bass combo:

(apols if, as I think, I’ve posted that one up already this year) and, of course, the same seller has plugged a particular gap in the market. Looking for a bass, mandolin, banjo and guitar in one body? Look no further…
