The sound of the guitar depends on the quality. I am not sure which guitar brand is better than the other but, I am happy with what I have for now. If only I can afford to buy a gadget like the Bigsby Vibratos which would definitely increases the tone and sustain.
When I play the guitar for hours, I just quit every time it is out of tune and it's a problem really. The tune won't stay long as it came loose from my strumming. I heard that this gadget can be of great help. And besides, the sound will be better too for it helps sustain the plucking. I will consider buying this anytime next month.
