Another curious question of mine, are claims of a BBD chip inside true? This is the cheapest 4-knob flanger I could find so I grabbed it for $10 shipped.
Inside I found an MN3207 BBD, an MN3102 Clock Generator, 2 x RC4558, and an "062C." Three trimpots all with the index mark at exactly 6:00 and 12:00, which makes me wonder if they'd been adjusted after assembly at all. I'm still playing with it before I dare adjust those.
