One mistake that many beginners make is that they purchase CHEAP guitars with high action and then they struggle with learning to play on it. This is setting yourself up for failure. Fail to plan, plan to fail is the old saying.
If you are committed to learning to play the guitar, save your money and buy a good guitar. The odds of you sticking with it are immensely greater, as the lower action will give you a fighting chance to make it. Better sounding instruments also will provide inspiration to continue practicing.
My recommendation is that you continue to suffer with your current guitar, while saving your money. If you can save another $400 to $500, you can get a really fine guitar on eBay. Recently, I was able to pick up a Takamine Supernatural series guitar that usually lists in the low to mid $2000 range.
This instrument was factory refurbished, meanng that upon final inspection, something was found that needed to be repaired before it coulc be sold. I did an extensive inspection, but couldn't find what they fixed. Other than the stamp on the back of the head stock saying USED, it was like a brand new instrument.
Any way, I purchased the instrument for $700 with free shipping. When it arrived, I was ecstatic, as this instrument sounds awesome. It has low action and is extremely easy to finger. Chords are very easy to change. For an extra $400 over what you have already, the additional value that I received was immense. I will never buy retail again. You just don't get the same bang for your buck.
The additional quality level could make a HUGE difference in how progress as a student or as a guitarist. Go to eBay and see for yourself that you CAN get a tremendous buy on a much better guitar.
Call the manager at Guitar Center and tell him that you are unhappy and want to return the guitar, then go to your parents and explain to them that you made a three hundred dollar mistake. Explain to them that a one hour trip is much better than a $300 loss. Be sure that you have your receipt and anything else needed to return the guitar, so that you don't have to make mulitple trips. Also, put out of your head the imagined fascination with the Seagull. Three hundred dollars retail, isn't going to buy you much. It is simply another cheap guitar.
However, I can assure you that if you are purchasing a quality instrument valued at $1500 to $2500, you will be happy with the value you receive. You simply do not get much for $300. Get you a part time job, save your money and buy an instrument that you can really enjoy and build on. I know this for a fact. I suffered thru lots of cheap guitars and I didn't improve until I got something that made it easy for me to learn and play. It is tough enough to learn the guitar without having to fight your instrument tooth and nail every step of the way.
