OK... newbie question here, so go easy. I'm refurbishing an old wood Martin-Freres bass clarinet and it's in great shape mechanically except the bell had a bad dent and the floor peg holder had snapped off and was missing. So I found a good deal on a Kessler bell with floor peg. Just tried it out and the tenon is a perfect fit but... the tone hole is a good deal smaller. Yup... I should have asked for dimensions. So... how bad do you think it would be to implement a smaller size tone hole in the bell? Will the pitch be sharp by a few cents or worse on open tones or could it almost be insignificant? It needs new pads something fierce but yeah, I might be able to get enough notes out and do a test, though in it's present condition, it would not be very "scientific." Like I said, go easy...
