Are stagg acoustic electric guitars nice?

it's a beginner guitar brand , as long as you think it sounds nice put some new strings on it every other month and keep it in tune , I mean it's 90% the player 10% the guitar that makes it good.

one tip , switch the guitar tuners to a brand such as Grover , Sperzel , Schaller or Gotoh. Good guitar tuners are essential to serious musicians. Try to replace the hardware (parts) with bone if you can as well it's a 10$ (at most) investment but you'll be steps closer to a professional guitar.
