Very true. As I was saying to you on FB, one of the problems with us "true lefties" is that the market is even smaller and less dynamic due to a number of left-handed people learning to play right-handed.
I've heard all the reasons - "playing a guitar is difficult in any case, so I may as well learn to play the kind that offers more options"; "I'm actually using my strong hand, the left, to fret as opposed to plucking" and so on and so forth. Quite apart from actually finding a lefty bass easier to play than a righty - cos I'm a lefty, duh - I make a point of trying to remind manufacturers that we exist, and would they mind at least making stuff ambidextrous, if possible. It's an uphill struggle.
