PDAL of optical cell volume (no knob who fouled under the pedals)
SETTING THE knob of a minimum volume,
PSU on 9v battery or transformer

UTILIZATION

Very easy to use, a knob argler, Souvant max and vroom-vroom we do with the pedals

SOUND QUALITY

His point of view it does not dnature indicates position max
and has the same effect on harmonic distortion and the volume of knob scratches during the race,
rponse linear ffective in "violing"
a minimum level adjustable allowing the passage of a rhythmic sounds using a lead sound that emerges from the mix without much map of Sonora and dynamics between the two
The small catch is that there is a break lgre sometimes audible when the RULES to mute the sound turned up

OVERALL OPINION

I have the pedals for a good ten years,
it is a robust evidence (not a single problem since I) notte thanks to its optical cell.
This is not the pedals I use most, but when I need it rpond always "present" with the same reliability and quality.
