I recently put Zyex light strings on my DB and I love the sound and feel and I'm wondering if anyone has tried them on an EUB. I have a Yamaha SLB 200 that has a well used set of D'Addario Helicore Pizzicato Mediums that are the factory recommended strings and they are sounding pretty dead and it is time to change them.Any comments or suggestions regarding switching to Zyex on the Yamaha?
