YouTube music has now been updated with EQ adjustments. With this latest feature, you can now tune the equalizer settings right from within the app. The change was first noticed a few weeks ago and is now seen to roll out to all the other users.
In YouTube's version 2.59, there is a new menu in the app's settings which is right below the Streaming Quality option. This EQ interface is said to be similar to the equaliser found in the Google Play Music App.
There are 12 presets available from which you can choose or you can also customise around five range sliders and also fine tune a bass boost or surround sound effect. This update is said to roll out on a per-user basis.
