Arrite, well my cousin let me have his old Martin Sigma. I've googled this, but they stopped making the series. I have the TB-1(the electro-acoustic one). It's a laminated top :l I'm not too fond of laminated tops. Anything on this guitar I should be happy/worry about?

Yep, it was basically a cheap brand, just like what Applause is to Ovation, Jasmine to Takamine, etc.

But as long as you didn't have to pay for it, that's not too much of a loss for you.
