in scales been i hard time why doguitarist pick different scale letters

Uh, I'm not sure what you are trying to say. If you mean why do guitarist play in different keys, it's because each key has its own sort of mood. If you mean why do the notes have letters associated with them, it's just the convention that people created a LONG time ago to build and understand relationships between notes.
Stop whining and learn your theory!

Yeah, some black guy with a yankees cap walks into the ice cream parlor, and I said "We dont serve your kind here," as in, yankee fans, i guess he thought something else and left.
