I have the schaller f121 volume pedal and its minimum volume is not completly quiet how to i adjust this i know you can beacuase someone said you move the gear shaft away from the pot?? This just confused me i opened it up and fiddled around but couldnt change the minimum volume.
Those are just a pot aren't they? If so, what is happening is the actuator shaft isn't turning the pot all the way to zero. You have to change how they mesh. To do that gently move the actuator away from the pot so it no longer meshes and turn the pot all the way down. Then drop the actuator shaft back onto the pot with the pedal in the minimum volume position. If you've done it right the pot should now turn through it's entire range as you move the pedal from min to max.
