So I decided rather than throwing it into the dustbin I would repair and rejuvenate my acoustic bass. things didn't go quite to plan, for many reasons chief among which is that I didn't bother finding out what and how I should do before I started filing drilling sawing hammering etc.
The action is almost playable now, nowhere near as much risk of anybody mistaking this fine instrument for something more usually seen at an Olympic archery event.
However the piezo pick up is producing some interesting results, specifically it can detect the E and D strings and indeed produces quite a pleasant sound. However, when I play the A and D strings it seems a little more reluctant to have anything to do with the whole performance.
Ideas? I did nothing other than remove it and wonder what it was and then replace it.
