I would love a nice (stereo) BBD flanger/chorus, but felt a bit fed-up with all the 'classic' designs, particularly the traditional clocking scheme, usually with a limited range, lack of current drive (to overcome capacitance of the BBD clock input) and strictly linear modulation (calling for a hyper-triangle modulation source).

Thanks for the link Terry - that was really interesting. What do you think he means on page 34 by the term “synchro-sonic” ?  Hard sync as in a synth waveform modulation? I wonder what that would sound like in an LFO driving a BBD? Pretty subtle I suspect...
