Explains how baffles fitted internally can reduce the volume
and/or change the tone of a Maccann Duet concertina,
and how the sound of each end can be controlled independently
so that the "balance" of an instrument can be altered.
The motivation for adding baffles is most often
to accompany a singer, to alter the sound-quality,
or to allow a right-hand melody to be heard while playing left-hand chords.
With 88 step-by-step photographs,
and web sources (UK and US) for all materials and tools needed.15 March 2002: Updated with photos of early Wheatstone wooden baffles (from Paul Hardy)
and of Lachenal linen linings cut out individually around every button (from Joe Palof).
Also added, a photo of a unique ten-sided Maccann Duet which, rather than quieting
the left end with baffles, instead makes the right end louder by doubling all
the reeds on the right side (now owned by Neil Wayne, photo from Stephen Chambers).
15 February 2003: Updated with photos and description of very early Pre-Maccann
Wheatstone Double Duet No. 23 (1847-1848) which was equipped at the factory with conventional
baffles on both sides plus a special baffle inside the reed pan on the left side--only--to
balance the volume of the two ends.
