So there are four notes = which are duplicated on either side of the bass/treble break then?

I haven't seen = it yet. What is it and basically, how does it work. These Ibach transposers are interesting. The one in Sydney we maintain = is owned by the Faber-Castell family (of pencil fame). There is a lever under the keyboard (under the treble end) which is = depressed then shifted to a new position to relocate the rest position = of the action (to select the desired key). When the 'shift' lever is = first depressed, it lifts the damper tray to avoid damper lever damage = when the action is shifted. The one we maintain, when at the 'key of C' position, has a standard = compass from A1 to A 85. The 'key position' can be adjusted four = semitones up and down from the C position. So the lowest note in the = bass is the F below A1 while the highest in the treble is C88. There are = extra notes either side of the bass/treble break which are required when = the action is shifted from the standard 'key of C' position. The plate = is made with a capo bar which extends through the entire compass of the = instrument, inverted agraffes are inserted into the capo to enable the = string positions to be evenly spaced from the bass/treble break to the = very highest note. The plate struts are quite elevated to allow for the = strings to be located under the struts where necessary. Tuning these instruments is an interesting exercise, since the 'scale' = is laid in the C position, then as the bass/treble break is approached = one needs to 'change gears' to the lowest key to tune all strings in the = tenor. Once the tenor is tuned one has to 'change gears' again to the = highest key, to tune the highest notes in the bass section. Then 'low = gear' needs to be found again the lowest notes in the bass. All in all, these 'formula 1' style tunings should attract a higher = fee. But then again, it makes a tuning day a little more interesting = than usual.
