Inherent problems? Two, basically:
1. It can't be intonated. At all. Period.
2. String height can't be adjusted. At all. Period.
It may be a nicer and better made
thing than this very simple wooden bridge, but; as a
bridge? The wooden one is actually much better. You
can adjust the string height, and it
will intonate (well, if you're lucky - but you can at least get close). That bridge is from a time when most players didn't worry about intonation much; if you were in tune, and the intonation was sorta close, then you were good to go. String height? Don't be a wuss... The reason nobody makes them any more is that nobody will make something nobody wants; and the reason an original one is so expensive is that 99.5% of them got thrown away as soon as the owner could yank the thing off the bass. Collector's want them because.. well, because they're collectors. They aren't going to actually try and play the bass with that thing on it; they just want it to be
Original...
