We're not quite there, soundwise... I did try about 10 locations on my bass, but anywhere I stick it, it sounds boxy, and without any interesting low end nor punch/definiteion. It adds a bit of natural texture when mixed with a good piezo pickup, but on it's own, it's a no-go for me! That's too bad because the form factor, with the small XLR plug mounted on the strings, is a good simple and sleek looking idea. Keep working on it, Schertler...
