Found a nice, albeit subtly different way to use the flanger. If you skip the internal oscillator in the flanger, but send a fast triangle LFO through the mod matrix to the flanger delay time knob, it does a different sounding thing than the regular flanger. Setting was
Delay time - 10 oclock
Regeneration - 10 oclock
Rate - 0
Width - just a tad to give some stereo width
Mix - 50/50
Sounded more leslie- like. That’s the Doppler effect, could possibly be improved by tricks people do making faux Leslie guitar effects- there’s a tremolo (amplitude modulation) aspect to the sound, as well as a tone change when the spinning horn is pointing away from you. Seems to sound more vintage with a less bassy sound, I liked the Steiner in hi-pass mode, just cutting out the lows.
