Sorry, no, you CAN'T! It's nessessary to use this three BBD chips with
two LFO's and a phase shift of LFO's amplitude to modulate the BBD's.

Have a look at http://www.sigmuntowski.de/pages/string-ensemble.html
(only in german), here you can read about the technics (also thanx to
Till Kopper once again!).

Please: never use this guitar chorus boxes - they're sounding too
good, like a real chorus. What we want is that string chorus ensemble
effect, not a clean chorus effect.

Best regards and peace to the world ;-)
