    Excellent once set up

    The guitar is now a pleasure to play. The factory setup made it an instrument that needed considerable force to control. A local guitar tech took the time to set it up to greatly enhance playability. It now has the classic 12-string sound, although a little light in the bass. Even with the cost of a setup, it still represents excellent value, something Sigma has always provided the consumer.
