I always had a problem on my d.bass. Let me try to explain... Well , my strings are too strong, the tension seems to be too high. I really have to strongly "push down" the fingers to reach the keyboard. I've tried to move a bit "up and down" the bridge but the things did not change too much. At the beginning all was natural to me... then I played some other d.basses and I constantly found the strings more and more light , easy to play... -so, maybe it's just a problem of type of strings? Any suggestions would be appreciated... my thanks in adv.
