Trying to find cause of ringing bell-like sound around 2627K

I’m recording an acoustic 6 steel string guitar and it’s producing no such ringing tones on its own.
You can see where the “bells” are in the spectogram. I’m also attaching an audio file–there are three “bells” in the beginning and then no bells (even though the input material is similar.)
I can minimize it by applying a narrow notch filter at about 2627k, but obviously I’d rather solve the problem at the recording stage.

Paul-L’s de-esser will do a better job than a notch filter : it only attenuates when the volume is above threshold , whereas a notch filter totally removes everything at that frequency throughout the entire duration of the track.


IMO the bell-sounds are a peculiarity of the steel-guitar, acoustic-resonance, rather than an electronic glitch.
You’re just not noticing the bells when you’re concentrating on playing , only hearing it on the playback.
