Yes i have, since the sad1024 consist of two 512 stages,
but, (isnt always there a "but" in everything!!... geee)
i had my doubths about this since the stages are a bit short
wich makes the clocking creep trough, alltought harmonic
but very high pitched!! ugh!

But the major problem i see with BBD are the shortening 
of note decay as one pitches up the resonator!

But what about this idea, use two tape reel machines crating
a PYMO synth!! Or a spring reverb as resonator! :-)
