UTILIZATION

Foot switch type TRUE BYPASS
3 potentiomtres of rglage:
1) VOLUME: no comment ...
2) SUSTAIN: level of compression (ratio)
3) TONE: mini: favors in the lower treble attnuant
middle: balance bass / treble
the max: low attenuation, mdium / treble forward
Note: rglage TONE is a particular kind filter bandpass (nothing to do with the classic tones that only cut the treble)
No need for manual, the ear is enough.

SOUND QUALITY

Sons: Unique! Nothing to do with a standard compressor. Many possibilities, from low to its large and high-sounding guitar funk with mid / high pops and incisive.
Trs warm sound, brings out the sound in a mix or in groups.
Used with an active bass and a stratovolcano, users (site Harmony Central) have branch with bass, guitar, Minimoog, drum tracks ... Nothing would rsiste!
PDAL silent trs little breath.

This is a must for aficionados of the seventies and a sound that is different from conventional compressors.
Trs rare and therefore taken into collection.
