Well, the forum states that the posts should not be disrespectful to anyone, so please understand that my reply is not intended to be in any way disrespectful, but rather an accurate explanation and assessment of what you are asking. Playing guitar consists of 2 components, physical dexterity and ability, and inherent musical talent. The first is almost never a "natural " gift and must be practiced and nurtured by the player for a period of time until the muscles and brain work in tandem to allow the body to execute the musical ideas in the players imagination. This is why there are so many good players out there that are not even 10 years old...they already have great musical minds and they practice just to improve their muscle memory and physical execution, which is pretty easy for the young bodies. The actual "musical " component is not going to appear in most people who don't already have it in their heads, regardless of how much they practice their physical execution. In other words, your musical mind is only limited by your ability to express your ideas in some physical manner, but even if you have the most awesome physical skills, you might not become a great player if you have limited musicality or natural talent. The fact that you say that you practiced endlessly and still have a hard time with your ability to hear accurate pitch leads me to believe that you have some limitations to your musical abilities and might not be entirely successful in your efforts, regardless of how good you can move your fingers. This is NOT to say that you are unable to get to the point where you might be able to eventually get good at this, but it is going to take a much longer time to try and develop a skill that you don't already have naturally, in fact, you might never be able to get a handle on this. Like a good Chef, you can learn everything about great recipes, combined ingredients, etc etc, but the dishes you create will suffer greatly if you have any issues with your sense of taste, or none at all.
