Technology: Analog

Made in Japan, 70/80 'a priori

4 knobs: "depth", "manual", "speed", "feedback"
Several adjustments, the knobs are accurate.

Powered by 9V battery or standard Boss adapter, used via a garland for me.

UTILIZATION

No (required) manual.

Adjustments are empirically, take a little time but the sound palette is wide and the result up to the expectations!

The switch on mine sometimes freezes, I have to press several times to trigger the effect (wear?).

SOUND QUALITY

Commonly used with a guitar, sometimes with a flute to color the sound.

The sound is warm, rich in harmonics.
Used on or Afro psychedelic atmospheres.

Very expressive in its clean, if coupled with an overdrive for more punch.

OVERALL OPINION

Used for about 2 years.

Initially I used occasionally built a micro-cube Roland flanger: I loved this effect but setting options via this amp was limited and rendering sound quite cold.

So I obtained the little box to "sculpt" a more accurate sound!
Happy with the result.

I do not remember having tested other models of its kind, difficult to compare.
