Very cool! I've been asking some parts makers like Warmoth and a couple smaller companies about Sassafras ever sine the EJ Stories Virginia Strat came out. None of them had it. I asked a smaller builder if they had a suggestion for a substitute and they said Northern Hard Ash but that would usually be heavy which surprised me.
I noticed that Novo guitars uses a lot of "Tempered Pine" but I don't even know what 'Tempered' means. But Samtheman posted that C3 amp demo using a Novo and that guitar/amp combo sounded great.
