projects using mn3207 or mn/bl3208

[haspelman]

Hi!

What existing projects like chorus, delay or flanger use mn3207 or mn/bl3208 ICs? All the projects I know use mn3007 or 3008. The 320x are quite cheap, so please tell me where to find good schemtic/layouts.

Thanks!

The AD-3208 project over at www.generalguitargadgets.com uses a trio (or pair if you want) of BL3208 chips.  As it happens, many of the BBD-based modulation pedals (chorus/flanger) that people want to build are old enough that they use the MN3007 rather than the 3207, but more recent versions of those pedals tend to use the 3207.  E.g., I'm pretty sure that the CE2 uses/used a 3207 in its later years.  I think later-release BF-2's also did, as did chorus and flanger pedals from other manufacturers that were made post-1985 or so.
