Has anyond had any experience with the Neuser Single String Bass Bridges w/ Switchable Fretless Sound? I was contemplating getting them for an OLP 5 that I'm pretty much gutting. The neck is very good (surprisingly) and I'm going to replace the electronics, pickups (going bart) and shave the body down a bit. So this is more of a fun project for a backup bass. But if these things work well, then I have another sound to add to the arsenal (ya' all know what I mean ). So any input would be greatly appreciated.
