Whenever I mute notes on my bass my strings still resonate, its like doing harmonics except you don't mean to, most strings do a short ring whilst others long and there is probably about 14 frets that just carry on playing the note altogether. I'm not sure what the issue is? it occurs when muting with my left hand (I am doing the proper muting technique) no matter how much pressure I put on the strings it still resonates, so Im not sure how i can fix the issue :/ I have an Ibanez sr405eqm
