Here are some base presets that I use when I don’t want to lug around one of the racks. They’re close enough to the AD-220 processing, but there’s no way I can replicate the sound of all of those MN3004 chips. The delay time ranges are exact, and the FILTER bandwidths add reasonably accurate limitations. Both DELAYs have duplicated values.
I adjust the FEEDBACK A & B and MOD DEPTH / MOD SPEED to fit the situation. DELAY A & B times are mapped to the expression pedal, and authentically ‘bend in pitch’. WET MIX (“Delay Level” in the AD-220) to taste.
- Effect Type: Delay
- Delay Range 20 ms – 500 ms [@ 700 Hz]
- Effect Type: Delay
- Delay Range 15 ms – 150 ms [@ 2.5 kHz]
- Effect Type: Delay
- Delay Range 10 ms – 75 ms [@ 5 kHz]
- Effect Type: Flanger
- Delay Range 1 ms to 22 ms [5 kHz***]
- (1 ms – 13 ms in some inaccuarte vintage advertisements)
*** OK, so I cheated on the 5 kHz. limits. I like to hear the ‘thru-0’ accents on the multiple-waveform flanging in all of their glory.
