Awesome, thank you. I guess I could always sand it down if it was too big
I'd take a rain check on that. It's never too big. The difference is mainly, with a fatback there isn't and slop down on the strat neck. Pic included. Click the link. I took a HUGE picture, but pictured in it for size ref is a standard 63mm Dunlop Tortex pick.
You can see what I mean about "no slope" from Headstock to Neck. The 59 roundback has a slope, the fatback/boatneck do not. I still recommend a fatback over the 59, though. It's that much more wood. Lotta tone.
