Pedal works fine!
Does its job very decent. I use it as a volume control for my Peavey 6505+ 112 combo and I put it in the effects loop. This way I have more detailed range for the volume on the amp itself.
The only thing I can remark is that the knob does not turn as smooth all around the range of the potmeter. turning from 0 to 50 percent, the knob loses 'smoothness' and becomes somewhat stiffer to turn. From 50 to 100 it becomes more and more smooth towards the 100%.
This does not affect the function and that's the only thing I can remark. In my opinion, great price/quality ratio.
