I have a 6 string Ken Smith bridge from a bass I built 12 years ago. After the first string up we went with another bridge to add RMC piezos and this came off. Playing time is under an hour, sitting in a box time about 12 years. These were quite expensive back then and I don't even see them on the KS site now. I'm open to any reasonable offer now and also open to trades for effects or a nice speaker cable. SOLD!
