I really really like this volume pedal. The action on it is very smooth and ideal for what I want to use the pedal for. I am using this on a cello that is running from a Schertler YELLOW blender into my pedal board. I have the volume pedal chained after my digitech whammy, mojo mojo overdrive, and Earthquaker bit commander. Then the volume pedal connects to my reverb, delay, and loop station. I found that the bit commander has such an intense sound that sometimes boosts the signal entirely too much, even if the level is set low. So the volume pedal allows me to set an appropriate listening level so that I am not blowing the ears off of anyone at a gig when I'm using the bit commander.
The signal is very clean and clear and it's brilliant that it's passive and does not require power.
The pedal is the junior version of the Ernie Ball, but it still takes up a sizable amount of space on my PedalTrain Classic 2, next to the Xotic X-1 wah and the Digitech Whammy.
Feature-wise, it's great that this pedal has a tuner out option so your tuner can be switched on at all times. I have a TC Electronic Polytune Mini connected and sometimes there is a pop when it is switched on and off. However, utilising the tuner out slot frees me from that pop. Overall a brilliant, brilliant, pedal.
