[sdiy] echo effect processor

[Pat Kammerer]

Hi all,

Has anyone run across one of these in their searching or scavenging?
http://www.cbtricks.com/database/datasheets/es56033.pdf

I've been breadboarding a bit with it, and I will more after I get done
moving.  (tired)  It seems somewhat promising.  It seems you can get an
audio VCO out of it, or an echo(delay) circuit. I'm thinking I'd rather go
with echo setup, because the VCO is probably poor.

Does anyone have any bright ideas on ways to use this other than what's in
the datasheet?

Thanks,
Pat
