I pur a set of bass guitar strings on today. The tesnion is ok. the nut is so high for the flobadob rubber strings that fretted notes on frets 1 and 2 are way out. 4 of the 5 machine heads only want to turn in one direction so I have had to reverse wind strings. I might have crushed the piezo to death. It is going well, and it is not going well. Structurally I think it might work. At the moment, it is not happy. I am not too bothered about the piezo cos I would change the bridge anyway.
