1970 Sigma Guitar - Do we look familiar?

That's right, we look like a Martin, we're not of course, but we know a good thing when we see it. And like a Martin we've got rosewood backs & sides and spruce tops and a lot of other goodies that make us more than just a pretty face. The amazing thing is that we sell for less than $150. We think you'll know a good thing when you hear and see us.
