Hi I have just purchased a bowlback from Ebay which is in good condition with low action (2mm on the 12th) - the only thing I am finding is I need to be careful to place my hand so am playing directly over the soundhole. The low bridge (which is fixed in place) means that there is a lack of clearance over the scratchplate and if my hand veers too close to the rosette edge the plectrum hits against it. It's my first bowlback so not sure if this is normal and just to train myself to play over the soundhole or is the bridge too low. Thanks.Attachment 194124
