Do you know what the the resulting difference is? Does it effect the range of the flanging effect, or the overall response of the pedal?
Here's why I ask - I mainly use my flanger for that clanging, Andy Summers Regatta de Blanc era sound (as opposed to the normal peaky up and down swoosh sound). For that Summers clang, I found that having tihe Manual control all the way down is best. This makes the center frequency of the sweep as low as possible (by moving the delay time out as long as possible.)
I'm wondering if the BF-2B's delay time range is longer than the BF-2's. Might make it "my" kind of flanger, at least for those days I'm not torturing my new Behringer Dimension Space C (I love that name).
Edit: Doh! I answered my own question at the
BOSSAREA.COM. The BF-2B's delay time range is exactly HALF of the BF-2's, so its frequency range should be an octave higher - not what I want at all. According to BOSSAREA, the idea was to leave the bass fundamentals alone, and flange the harmonics. Learn sumpin' new every day.
