<< >I've always wanted to know: what are "bucket brigade" components??? >> pre-digital sampling. these chips contain a whole load of capacitors (typically 512 or 1024 they take a sample by storing a voltage on a capacitor. then at each clock cycle the 'sample' is passed along to the next capacitor along. at the end of the chain the signal is recreated. a kind of analogue sampling which was used for audio delays. by accepting a low bandwidth and with multiple chips you could have an echo unit. or more commonly a flanger (EH etc) being non-digital these devices are actually quite easy to modify for bizarre sounds, although the sound quality is a bit basic. just like when 'brigades' of folks try to put out a fire by passing along 'buckets' of water. ...well ...someone did ask Andy Butler Lexicon Vortex Database http://members.aol.com/soundfnr/vortex.htm
