What is it worth if anything?

Contact Taylor to see if it's registered to the seller.

according to Taylor data base that number doesn't exist, please double check and go to taylor serial number lookup website.

The Taylor 307GB, or the "Big Baby" sells for around $250.00 on EBay, a little more on Craigslist

Try doing an online search for that guitar and check results for current listings others are offering them for. Check eBay too for similar info. This can be done to get a rough idea, but the actual condition of yours will affect value.

string like you would a right hand guitar for a right hand player so when you face a right handed player, it appears to both of you that you are sort of looking in a mirror. It makes it easier to learn that way too.

My son has a Takamine acoustic/electric. He plays in a band an is very accomplished. He and I both like the Takamine. He had a Fender acoustic/electric and sold it to keep the Tak. I have a hand made acoustic that I play at church. I like his Taka better. And I'm sure it's cheaper than another Taylor. The Tak. doesn't compare to the Taylor but it is a nice guitar and the electronics are good. One guy's opinion.

Thanks for using FixYa.

You are likely correct that you have trained the battery. The battery is located at near the tail line.

Replace the battery. Batteries tend to recover and then go down again when they get weak. Use GOOD alkaline batteries NEVER rechargeable types.

Yup. It sucks pretty bad.

If you just bought the guitar, take it back. Taylor has good warranty programs, take it back to the dealer. You may have a bad connection inside where the saddle pick up plugs into the graphic preamp, the fact that you hear a sound when you put the battery in or out indicates very little. You may have a bad preamp, like I said, if its new, don't wait get it back to the dealer or contact Taylor.
