cause im going to learn to play guitar and electric guitars are EXPENCIVE so im thinking about starting out on a cheap acoustic till i have enough cash for electric
So far, good answers; yes, most people start on acoustic. Yes, a cheap acoustic may very well be a piece of junk that won’t last and will be hard to play.
So let me take this a bit further for you–everything a beginner should think about–
1) Instrument: go to a very good music store–a Sam Ash, Guitar Center, or the big local shop that sells orchestral and band instruments. These stores don’t sell junk. Try out as many guitars as you can in your price range (or slightly above). Try them out for feel–even if you don’t play yet, you can put the neck in your left hand and see if the fingers feel good pressing on all strings, you can strum right the right hand and see how the arm likes being draped over that body.
Once you have several that feel good, have a sales clerk or a friend play the same tunes on each while you turn your back. This blind listening test is the best way to judge the sound.
Now, since you’re on a budget, the next step is to wait for one of your preferred models to go on discount–or to find one online at ebay (only get one that comes with warranty), http://www.musiciansfriend.com or maybe even http://www.shopgoodwill.com but if it’s goodwill, you’ll need maybe another $100 in reserve in case you need to take it to a repair shop (try one of those music stores listed above) for adjustments.
2) Find a teacher. As a beginner, you’ll make lots of mistakes, and you won’t catch all of them. If you don’t get the right fundamentals at first, you risk long-term not being able to play up to your potential, and maybe even getting nerve and joint repetitive motion injuries.
Cheapest teachers are found by putting a note on a bulleting board at the music department of a local college and landing a guitar major. Second choice would be to try one of the music stores listed above.
After about a dozen lessons, your fundamentals will be sound; then you can drop lessons and self-educate. Try getting books, cds, dvds, etc. from ebay–you’ll save money.
3) Plan to practice for not more than ten minutes at a time, several times a day, at first. This yields fastest progress. Second week, extend the time up to 12 minutes–and keep going up a couple of minutes a week, eventually dropping back to 4 then 3 then 2 practices, until you’ve built the stamina and knowledge to benefit from a one-hour practice (or longer) daily.
