"Do you mean you want reccomendations of white male singers who were really good, or white male singers who made the best of their idiosyncratic vocal "talents"?"

The second. Actually I don't think my range is much of a problem. It's not athletically impressive, but I have from G, to D' with reasonable comfort. Like Matt, the higher I go the less I like it. And heaven forfend lest I should find somebody to try to "copy". But I am interested in white, male, blues-influenced singer-guitarists who have found ways of making a perhaps limited voice "work" for them.

Although, if I may say so, Bert Jansch could not sing for toffee. I say that with great respect, as it was wearing a couple of his LPs flat that informed my first explorations of the guitar. But I have seen people who did not know his work start to look very uncomfortable indeed once he opened his mouth.
