Is this bass noise normal?

[hotinroof]

Hello I am an absolute beginner and I have just purchased what seems to be a fairly recent 72 bass Weltmeister in seemingly very good condition from a decent music shop. But there seems to be a sonic distortion at the end of the bass sounds which seems like a resonance or something loose (sounds to me like low bitrate audio artefacts). It could be normal and something to be expected? Hoping someone can give me their advice. Short audio recording here.

hotinroof: I can hear low reeds taking their normal fraction of a second to stop sounding/vibrating. Perhaps it's my ear and/or your recording that makes me think that. Is there a coupler on the bass end which will stop the lowest reeds sounding? If so it might be interesting to then hear the sound.
If there is no coupler then you can try isolating the reeds by inserting a piece of paper under the reed blocks, to cut them off. Opening up the instrument would also allow you to check if there was anything loose in there which might be responsible for the 'resonance' you say might be there.

Thank you very much for taking the time to reply and listen to my recording. The recording is a pretty accurate version of what's going on so if you think it sounds as it should then that's good. There's no coupler on the bass end so I might open it up and do as you suggest if I feel brave! Cheers.

It does not sound normal to me. The decay on low notes is not instantaneous, but still should be much quicker than the notes in your recording.

It's normal, though perhaps more pronounced than most on yours. The greater inertia of the lowest, weighted reeds will cause them to continue swinging for a second after airflow has stopped, making a sound like a plucked Jew's harp. There may be a bit of flutter from the reed valves mixed in as well, if they are plastic.

It sounds like the notes stop because you stop pulling or pushing the bellows, not by releasing the button. If you are releasing the button and it sounds like this then the "growl" is a bit excessive. If you stopped pulling without releasing the button then thr growl is normal.

I think you’ve hit the nail on the head. Pleased to hear that it’s operator error rather than hardware, thank you.

What a fascinating instrument. It sounds very much like a distorted electric guitar. No wonder it was used to evoke the sound of Hell back in the day.

Low bass reed growl. is so characteristic of acoustic accordions that Roland included it as a switchable feature in their virtual accordions. It's the player's preference whether to keep it on or off. I keep mine off, because it's not very realistic. Yours seems a bit excessive to me. Try playing as Paul suggested/

Yes, it is absolutely normal sound. Feel free to continue playing.
