so ive been playin guitar for something like 4 or 5 years now, completely self taught, and i think ive progressed pretty well. lately tho i feel like ive hit a wall in my ability and i dont really have the drive to improve like i did when i first started. so i was looking into getting the complete guitar course from metal method, and was just wondering if anyone here has it, and if its worth it. will it give me what i need to further advance my playing so i dont keep playing the same old stuff?
