Sigma Guitars

In the late 1960s, affordable Japan-made guitars that closely resembled American models were flooding the market and threatening US makers. Rather than pursue legal action, some US companies responded by creating their own overseas lines. That’s how Sigma Guitars began: launched in 1970 and built in top Japanese factories, then inspected in the US before sale.

Sigma quickly earned a strong reputation for impressive build and sound quality. Many owners still cherish their instruments, which is why used Sigmas are rare. Today, the brand has loyal fans, online communities, and dedicated collectors.
