Need fx pedal schemes, esp flangers

[Harry Bissell]

I Disa-Disagree...

The S/H aperture time of the BBD is a function of clock frequency... as the
clock drops
the aperture time (read averaging time) gets larger... Yes you can
theoretically get "any level" within the small range between noise floor and
clipping. But it is the average value for that period... That is a form of
quantization... its S/H but the level is flat at any output point (if you
neglect the massive clock glitches...)

Its just as possible to get wide sweeps with a digital system if you are
willing to accept the same level of (poor) performance. Most people just don't
want to...

It is indeed low-cost (I avoid the "C" word) and easy to implement. You can get
a simple system with little effort... IMHO a complex system just isn't worth
the effort...

BTW...
HEY I just got a "Big Briar" catalog... Bob says he bought the last analog
delay chips that
will ever be made... and offers us his Analog Delay MoogerFooger for only
$595... in a limited edition of 1000....

Think I'll be getting one ???????
