Lehle Stereo Volume Guitar Pedal

The Lehle Stereo Volume is a volume pedal equipped with a precise magnetic sensor enabling it to operate almost wear-free. This sensor uses the Hall effect, named after Edwin Hall, to measure the strength of magnetic fields. In the Lehle Stereo Volume, the Hall sensor, which is made in Germany, is accurately calibrated to the built-in magnet and the control range of the pedal. The pedal moves only the magnet, the distance is measured by the Hall sensor which controls a VCA.

A premium Blackmer® Stereo-VCA (= Voltage Controlled Amplifier) from the United States replaces here in this case the mechanical potentiometer. The principle of the voltage-controlled amplifier is based on the fact that gain can be varied by the control voltage coming from the Hall sensor. This technique allows it to operate more precisely than conventional mechanical potentiometers or optical sensors used by the standard volume pedals. In addition, the potentiometer-typicalnoise and the complicated adjustment are eliminated.

Over the entire control range the Lehle Stereo Volume transmits the full sound spectrum of the connected instrument. The input and output impedance always stay the same, ensuring that there will be no damping of higher frequencies as with potentiometers.
