Well - my fingers aint telling me no lies!
I am sure that Mica is right in certain circumstances for SOME people - I dont like statements like right and wrong ...each person must find their own right and wrong.
Brian May was ridiculed for using Oak as one of the primary woods on his homemade guitar (because the snobby purists insist it cannot be used as a tonewood) before Queen became famous - but it sounded good enough to millions of Queen fans.
Ebony IS a wonderful fingerboard choice, however, by limiting limit your choice to Maple Rosewood or Ebony you miss the chance to find out the qualities of other options.
If it works for you as an individual...it works for you.
I heartily recomend Cocobolo as a fingerboard..players should give it a try!
