Wha basic, no trimming.

UTILIZATION

No manual, no need either.

SOUND QUALITY

My first and worst wah I've used.
His aggressive, breathing, spitting, no effective when placed before the distortion, a very low position "back" rather limited range, of course, not transparently.

OVERALL OPINION

Purchased in 1983 for 135 f!
She gave me time service that filter in static position.
I do not really understand the craze and ratings for this pedal.
