Does anyone know where I can purchase small ampont of Rock maple (or maybe graphite for an EUB bridge. I's not a standard shape so I just need like a 4" X 4" piece. Any other material suggestions are welcomed. This is my 1st EUB so I'm experimenting a lot with it. I just bought a EUB from a guy named Jessie Blue in tennesse. Hand made. Took a lot of set up, but the bass was very nice. Very simle. Anyone else had any experience with his basses (ERGO is the name). Just curious. Tom T.
