Sigma SE Series GM12E Electro Acoustic In Blackburst

Your First 12-String?

Written by

Will Brook-Jones

This 12-string acoustic from Sigma is a stunning piece of guitar craftsmanship. If you’re searching for an entry point into the world of 12-strings, then this GM12E-BKB is the ideal remedy.

Sigma SE Acoustic Series - Simple & Affordable PLUS A 7-String Guitar… WHAT?!

Build Quality

The guitar consists of a large body built from a carefully selected sitka spruce top, complimented by a mahogany back and sides. The low-profile mahogany neck and a sigma acoustic pickup completes proceedings. The result of this construction is a guitar with a tonne of tonal variety and astounding clarity, that works to deliver a really balanced sound. Not to mention that fact that 12-strings (as opposed to your traditional 6) provides far more creative scope.

Electronics Excellence

The Sigma pickup included here helps to truly capture the voice and nuance of the instrument when amplified. Additional tonal controls – including treble, middle, and bass – then give you the option of tweaking your sound on-the-fly. There’s even an onboard tuner, so there’s absolutely no excuses for when you leave your tuner at home!
