Mono Volume : One flaw

The good:

Exceptional quality.

Excellent sound that doesn't compromise the highs in any position of the pedal and the dynamics of your playing.

These are the selling points and they did a wonderful job at Lehle.

The OK:

Good sweep but not quite like the one on the ernie ball MVP.

Quite difficult to leave the pedal in the desired position. I did tighten the screw but it has not much resistance. The ernie ball MVP again is better at this.

The Bad

The buffer does add some noise/hum. It's not something huge, you have to listen carefully but if you have already some hum from your high gain amp it might bother you. If you play clean I don't think you will have any problem. Again the ernie ball MVP doesn't add any noise but it doesn't sound as good as the lehle in any position and you lose some dynamics.
