I'm considering buying a Bahnson Overblow harp (I've seen one on special offer). Does anybody out there have any experience with them? Good or bad? It sounds like fun, but I would like to know if they're worth buying. I mean, I can play overblows to a certain extent, but not well enough yet to use them in my regular music-making. Training-wheels of some kind would be handy! All the best, Tom. p.s. does anybody know where I can buy valves (windsavers) in the UK? I want to set about half-valving most of my diatonics. I bought an MR350V, and I've found that the valved bends allow me to play in at least 6 keys on one harp without much difficulty at all. Well worth a go.
