In another thread: Boyd Wheatstone Concertinas BW77 mentions some experiments with muting the volume of selected reeds:
I have tried a leather baffle on the LHS of my Peacock and while it reduced the volume it also changed the tone. Most of the time I don't use the baffle. Another problem is that it reduces the volume of all of the reeds on that side, whereas I only want to lower the volume of the lowest reeds.
I tried 'feathering' the bass buttons with my fingers to see if I could get a decent volume reduction with a very slight button press, but there seems to be quite a cliff edge between sound and no sound so I am not sure if this technique will work for me. I might try some additional washers to see what happens - it is a simple, non-destructive experiment.
Then BW77 mentions taping over the pad holes with 'quite interesting' results. Please elucidate.
Is that interesting in a good way or a bad way?
