ADA Flanger

From Guitar Player Magazine (June 1995 -"Stompbox Fever" article)

This hard to find box is, in our humble opinion, the undisputed kabala of the flange world.

Given the amount of effort Charlie (moosapotamus) put into the DIYS ADA, this page needs some serious attention. A good idea would be to go through the threads (one currently being 28 pages long) and pull the data out. Anybody?

Background

The original ADA Flanger uses the long discontinued SAD1024 BBD chip, Charlie (Moosapotamus) and Dave W (OldSchoolAnalog) have combined to offer an update that uses either a modern MN3207 or MN3007 BBD instead.
