The Leveline is very well made, not only is its design rather smart and attractive to the eye, but it also a sturdy pedal.
Its size will make it a great fit for any pedalboard, however this size come at some cost. Smooth volume swells, though not impossible, are not as efficient as on larger pedals. It seems as though the pedal works "exponential".
It takes some getting used to and it can work, but a full-size volume pedal might be a better option for you depending on what you want.
