I have owned mine for the last 15yrs from new and have for the last 18mths experienced serious sound problems, no longer any attack from the instrument and have lost all lower end. The strings and bridge have all been replaced but the sound is still lacking. Would previously have penetrated the loudest of big bands but now won't even penetrate a small jazz quartet! Any ideas fellow bassists? Just to let you know I have been working with the makers (Bridge Violins) for the last 18mths but still the problem persists, getting really fed up with it now. I've even bought a Mark Bass rig so that is not the problem!! Thanks for your help.
