I just got a used SLB 200 with D'Addario Pizzicatos on it.The bridge is adjusted as low as it can go and the strings still seem high,especially at the nut.I'm used to BG and a Stagg and the action on this is higher than the Stagg and it is much more work to play-yeah,I know "real" uprights are tough to play but this Yammie is not like an identical one I have played.What string heights are reasonable on this at the nut and bridge?Any suggestions would be appreciated.
