IF you have a press, this is a easy fix. Look on the cam/cams to see if they can be adjusted. You might look the cam up on the internet to see where the string needs to be set. If there is no adjustment, or not enough on the cam/cams; tighten the bus and losen the string (make sure to keep your cam in time). Do this bytwisting. Dont over do it. As far as price, dont know. I would think it would be cheap. its not a major job, unless the cams need to be replaced to get more draw.
