Got the straps from Bodean over at Strat Talk.
Great guy, recently divorced.
Not cheap, but not excessive for what they are.
Quality veg-tanned leather... not the cardboard-like crap on mass-produced "nice" straps.
Like the DSG guitars, Bo works with you to give you exactly what you want.
I got the snakeskin strap because of one such screwup... I had bought the celtic strap and expressed interest in a 2nd one.
He was making the diamondback for another member.
The buyer wanted a concho on the end where the semi-circular cutout is. He screwed up and didn't provide enough material for the concho and still have enough clear leather between it and the end for a 335/SG.
So he re-made the strap properly, and offered me first right of refusal... I bought it, and he stained it to match the Lester.
