Hi all.
I'm looking at building a Mistress type flanger and having found really good plans/posts/info for TDA1022 (EM1022) and MN3207 (EM3207) here I am seriously considering building one of these. The question is which one would you people recommend most?
Also, I'd like to thank everyone here for sharing their efforts and for the time put into this site and projects with a special thanks to Thomeeque for the EM1022 and EM3207 projects.
Hi, my pleasure
Definitely build one, you won't regret it
Are you able to get TDA1022 chip? With this chip you have theoretically better chance to get closer to the original EM character thanks to the same delay line length as the original EM used (512 cells). MN3x07 is twice longer and I (nor anybody else I know) did not succeed to make it work in the same delay range without unwanted side-effects. But there are other criteria (mainly gain/frequency and gain/clock characteristics), which differ between TDA and SAD anyway, that's why I say "theoretically". EM1022 project gives more added features (odd/even switch, volume knob, vibrato etc.) too, that's another fact to consider (you could add all these features to the EM3207 as well, but it's not there by default).
EM3207 on the other hand is simplier build and MN3x07 chips are easier to buy. If you want simple EM like flanger, choose EM3207, I probably would.
Both projects (all three actually, there's EM3007 yet) are verified.
See demos, suit yourself, good luck.
