That’s odd because my AO 50’s has a 9.5” radius And not compound
At least that’s what’s advertised anyway. I’ve not measured it though.
Got news for ya. After pouring over the Pinecaster data I’ve found something I didn’t know:
Many, many extant Esquire, Broadcaster and Nocaster guitars were 9.5” radius Some were even 7.25/9.5 inch compound radius necks. The 7.25” boards didn’t start showing up until the Blackguard era. So the blanket statement that 7.25” is vintage holds no water at all.
