This is the classic Sigma JR 40 acoustic guitar. This Jumbo instrument produces a stunning rich wave of tone that will impress all who get the chance to sample it. This guitar has a powerful rich voice that has plenty of bottom end and a clear top end with great definition. This Sigma JR 40 is a strummers dream but will also work well with any style as it has a comfortable well designed neck. Unlike some other instruments of this size the JR 40 does not lose the clarity in the mid range, this is a great all round big sounding acoustic guitar. A real singer songwriters dream. Sigma have been building guitars since the 1970's and have developed a world wide fan bass and a well deserved reputation for producing superior performing instruments at very modest price points. This guitar is finished to a high standard and features some great specifications.
