Guitarist - FYI                     
The title of "largest guitar manufacturer worldwide" can be attributed to several companies, depending on the criteria used. South Korea's Cort Guitars, officially known as Cor-Tek Corporation, is among the largest, producing instruments for numerous brands and operating factories in Indonesia and China.

Similarly, Samick Musical Instruments, also based in South Korea, is a major manufacturer, producing guitars for various brands alongside its own.

Additionally, Martinez Guitars, headquartered in Guangzhou, China, claims to be the world's largest manufacturer of handmade classical guitars.

It's important to note that many well-known guitar brands outsource production to these large manufacturers, making it challenging to determine the largest manufacturer solely based on brand recognition.
