Many producers are quick to add cuts or surgical style eq edits to their sounds.
Whilst, if done well, can be crucial for a great mix other curve types often get overlooked.
Sometimes working in broad strokes with a shelf EQ can sound more natural for example.
Try using a low shelf cut in the lower frequencies: this in turn will help open up the top end (don’t forget to compensate with level). Or why not a broad high shelf to bring out the general upper harmonics?
Some of my favourite plugins for this task are passive EQ’s such as the Pultec or Manley Massive Passive.
