I'm looking to either defret the next bass I buy or replace its fingerboard with ebony. First question:What fingerboard woods defret well? Which do not? Second Q:What would the price difference be between defretting and fb replacement? Third Q:How about tonal advantages of certain woods? which will give me a very growly tone? And Q nubmer 4: What woods will take fingerwear well and where can I find the polyester coating used by pedulla? Thanks Folks!
