Non-clock-based analog delay chips? Never heard of these. How do they work?>>

Just to clarify, I was referring to digital delays (DDL's), not analog 
delays.  By "clock-based DDL" I meant digital delays that have a hardware 
clock specifically for clocking the delay shift registers, such as the Roland 
SDE3000 or the old DeltaLabs delays.  This is in contrast to many modern 
digital delays which do not have a dedicated hardware clock that controls the 
rate of the shift register.  Examples this would be any of these new 
DSP-based multi-effect units from Lexicon, Alesis, Roland, Yamaha, and pretty 
much everybody else.  Of course, strictly speaking, these units do have a 
clock, but it's the master clock for the DSP, and you're certainly not going 
to be sweeping it with an LFO to get a flange effect!
