Pink
Hope that that Luna pink guitar is easy to play and not like trying to pedal a pink mo-ped up a steep hill on a rocky road, when you really want thunder road. That can be what frustrates you and makes it difficult. Hopefully you will be alright. It certainly looks good.
Think about IMMEDIATELY putting on some extra light guage acoustic strings, about seven dollars. They are WAY easier to play, push down on, etc., than thick heavy strings. Look at the fattest string, the one on top when you play: you want this to be as thin as possible. They come in acoustic guages like what are called 10's, 11's, 12's, and 13's.
10's are what you might want because of ease of play and easier on your fingers. The 10 refers to 0.010 of an inch in diameter of the thinnest string on the guitar, the one on the bottom when playing. That's one one hundredth of an inch thick, or ten thousandths of an inch thick (this is where the 10 in the 10 guage comes from: 10/1000ths of an inch diameter), pretty thin indeed and easy to break. You might want to get a couple extra "single" ones, that are about a dollar each and come in very handy and save you the cost of buying a whole new set of strings when you only break one, usually these last two very thin strings.
People sometimes move up from tens toward thirteens as they progress in their playing skills and develop stronger more agile hands; then again some don't change sizes and play very lightly.
Another super excellent idea is that when you get your new guitar take it to a good guitar tech at a good store, that you obviously didn't buy it from - but they don't care - and have it "set up". Let them put the strings on and adjust the neck, nut, bridge and other parts like the tuners for you - things you don't know about but will make the guitar play WAY easier, better, and sound way better. This will add to your playing enjoyment big time.
When you get the guitar look at the bottom of the finger board by the soundhole and see how far the strings are off of the top of the dark brown wood finger board with the frets on it. The strings should not be way up in the air but only about a quarter of an inch above the finger board at the bottom of the fingerboard by the sound hole.
If the strings are a half inch up in the air at that point, have the guitar tech doing the set up bring the strings down lower to the body. This will make it much easier to press down on the strings and easier on your fingertips and hand. Electric guitars typically have the strings much closer to the fingerboard and require way less pressing down on the strings with your fingertips to hit the note.
A set up for a beginner that doesn't know much about what we are talking about will be a MAJOR thing to improve the guitars playability and sound.
Don't forget to put new strings on even if the original ones seem good, because they are probably old, cheap, Asian strings installed by the mfg and will have poor sound to them compared to some new D'darrio acoustic strings, no affln., or Martin strings, etc. Phosphor Bronze strings sound mellower and 80/20 Bronze strings sound brighter and twangier.
You are going to want to get your guitar sounding real good and playing real good. The best guitar shops in town usually have qualified guitar techs that know incredible amounts of things about making a guitar sound good.
Another thing you should definitely consider to purchase when you can is a real good "acoustic" guitar amplifier - not a regular guitar amplifier. Acoustic amplifiers can be found on ebay as well. Some good names are Fishman, AER, Fender, Crate, Marshall - that's about all I can think of right now. A lot of the other ones are not very good sounding and lack MAJOR features.
A good acoustic guitar amp has two "channels" with one that you can plug in a microphone or another guitar if playing with someone like a friend, or having someone else sing. The decent amps have anti feedback circuits to calm down acoustic guitar's amplified sounds which sometimes want to "squeal".
I have a Crate Gunnison which is a nice acoustic amp with a microphone channel and some built in effects and wasn't expensive. Avoid cheap amplifiers.
One rule of thumbs with guitars is: a good amp can make a poor sounding guitar sound great; a junk amp will make a great guitar sound like junk. So the amp is a KEY part of the sound.
If you want to keep up your enthusiasm you should consider getting your guitar set up with extra light strings, get a full set up by a pro tech, and get a decent acoustic amp. The amp will make it easier to play and less tiring on your hand and arm because you will just have to barely touch the strings to get a full loud sound and you will be able to tailor the sound to get a super nice tone.
I hope all this info doesn't turn you off, but it's like motorcycles - there is a lot to learn and it is sort of like a sub culture with it's own language, knowledge base, etc. Know what I mean?
Hope this helps. The Luna looks super cool, but get it set up real good by a pro. You will be very glad you did. Otherwise it will be like an out of tune motorcycle that hasn't had any service at all, wobbley funky tires, bent handlebars, etc.
Good luck with it. Electric guitars are less frustrating and have thinner strings and are way easier to play, if you want to consider one in the future.
