From an original Arion product description:
“The SFL-1 Stereo Flanger Effects pedal utilizes Arion’s quality low-noise modulation pedal technology. The Arion Stereo Flanger utilizes four controls to offer more sound variations than competing flanger effects.”
“The SFL-1 Stereo Flanger generates dynamic wavering sound by delaying the sound and many melodic effects in between, incorporating BBD (bucket brigade) technology. The principal is similar to that of chorus but the speed of the frequency change can be covered to the slower ranges. Therefore, the width of the signal delay is wider and various types of sound and vibrato sounds can be obtained.”
“Other advantages are the stereo effect from OUT 2 by selecting the mode switch with 2 amplifiers.”
“Arion’s Stereo Flanger Effects Pedal features an easy-open battery compartment for simple 9-volt operation.”
