Well, my new Irig Blue Turn pedal works a treat. So it appears that my old page turner pedal was malfunctioning. It has now been 'retired' from service. The Irig pedal is more expensive than some other page turners. But IMHO it's worth it , as it is a class product. Interestingly, it is manufactured in Italy, which may explain why it's more pricey than many of the far-eastern made pedals on the market...
