David Hornett Posted October 10, 2012 Share Posted October 10, 2012 Hi all, I am in the process of completely restoring a Jeffries Bros Duet and have got to the tuning stage. (So far completed: New 7 fold kangaroo skinned bellows, in the heavy Jeffries style, / papers / tooling / hand-straps / pallets / valves / reglued frame / bushings -- all animal glued.) There are a few peculiarities about this instrument: although it has the raised duet ends, it seems to have started life as a 37 button anglo. I believe this because the added notes button guides have been soldered on the inside of the instrument, both sides, and don't pass through wooden guides, and the added buttons very neatly and precisely passed through the fretwork. The air-button has changed sides to become C# on the left hand (Being a duet there is no need of an air-button). When the instrument is opened one can see where the peg and pin were on the right side for the airbutton. New reed mounts have been added and the old reed and air holes closed up with dowel. Some reeds have been remounted, former large and small reed slots packed out. And finally the pegs mounting board has on both sides been scooped our to allow for the pallets of the extra keys to cover the added reeds. The whole thing has been done most professionally, and I doubt very much if a backyard handyman could have done this, I certainly would never have attempted it. The instrument is in 'G' (an octave below the G on a standard C/G) A456, and pretty much in tune except for a few random stray notes. Now my question for you to ponder: In tuning do I file and take it up about 40 cents to 'D', or silver solder weight the notes and take them down about 60 cents to A440 'G', or leave it at 'G' A456; meaning barely a soul except for the violins can play with it? OR Do I restore it entirely to a 38 button anglo? OR Do I tune it entirely to goodness know what, keeping its 44 keys: this depends on changing at least half the reeds by filing and weighing, because being a duet they are the same note push and pull? I hesitate to silver solder notes, because although most accept it nicely, in does alter the tone at some frequencies and , for the few notes affected turns them from mellow to more of an ear cutting scream: been there done that! As it is, it is beautifully mellow instrument, with a growl, volume and response that would knock most concertinas out of the room. Suggestions? When tuned I will sell it as I don't play duets, so just maybe I should anglofie it??? So, what do you think? David Quote Link to comment Share on other sites More sharing options...
