sometimes the effect is desired and sometimes not. You get to decide how you want it to sound.
There are several ways to mute strings depending on where you find your fingers and which strings to mute. All of the ways are addressed here in our daily challenges. One of those techniques is palm muting, another is to dampen a string with your fretting fingers by letting your finger leak off of the string it is fretting to touch the string you want to dampen. It can also be done by briefly touching the string with the flat pick. This can be used to great effect. It creates a chirping sound.
Enjoy the sound and play with it. see if you like it or if it starts to bug you. It is only bad if you don’t want it there and can’t figure out how to get rid of it. ; )
