Nothing better than a dark chocolate EIR fingerboard on say, a Oly White Strat. Or Vintage White Tele... I built a kinda pastel/magenta pink Tele this year (definitely not Shell Pink), and the neck has a lovely slab board that I got from StewMac. Nothing special, just EIR, like $15, but gorgeous. Tonally, I don't hear a difference in fingerboard materials. At least I don't think so. I like rosewood and maple on Teles, and rosewood on everything else (of course). Totally agree with Kevin. Guitar use of EIR is not an environmental assault. It's just a reasonable use of a sustainable commodity, the name of which has been in the news lately. Very much like the Genuine Mahogany I bought for a furniture build, which was grown on a planatation in Fiji. Great wood.
