Custom guitar maker strikes the right chord in music city

"Every step is critical to quality," Peng said, adding that balancing a guitar's treble, mid and bass ranges and adjusting it to play at the correct pitch is challenging.

Most of Peng's customers are either music lovers, performers or teachers who get to know him at exhibitions or at cultural festivals.

His guitars sell for anything from 5,000 yuan ($685) to tens of thousands of yuan.

"The price differs based on the material and the amount of work I've put into it," he said.
