Is there a name for the type of fingerboard Daxun Zhang and Edgar Meyer have on their basses. By the type of fingerboard i mean the ones that have an extension for the G string like the one pictured below. I'm really fond of my bass and would rather replace the fingerboard than search for a new bass but don't really know how to begin searching for a shop that could do this or where i could get a fingerboard so i could have a shop replace mine, if you can even get them new.
Anyways, the reason for me looking for one of these is because i've just started Massenet : "Meditation" From Thaïs and since i'm studying at northwestern next year (daxun plays it an octave above everyone else) i need more fingerboard to get the high notes.
