First, let's focus on the guitar. This is the first acoustic guitar that I purchased back in April 2005. I was blown away by the sound right off the bat. The guitar holds up very nicely. Being a low-priced guitar, everything is not perfect. The nut is plastic and not real bone, but the plastic appears to be sturdy and four years later it is still in place. The bridge (for the price of the guitar) is shockingly high quality and allows the guitar to produce a very professional tone. This guitar rings like a charm. It's an all around great guitar. Especially for a beginner, but not limited to beginners.
Now to the package. This specific package was introduced in January 2003. The worst part of this pack is the gig bag and pitch pipe, which is relatively useless for tuning your guitar. You will absolutely want to purchase an automatic, electric tuner. Especially when you become more skilled and want to explore alternate tunings. The pitch pipe is trash and I threw it away promptly. As for the gig bag, it isn't up to par at all. It doesn't protect the guitar and is more likely to knock it out of tune than protect from scratches and nicks. In fact, the gig bag might even cause some scratches to your guitar.
Fender has updated the SA-100 package and now includes a better automatic, electronic tuner, so I recommend going with the new package.
