{"product_id":"lehle-mono-volume-pedal-mint-w-box","title":"Lehle Mono Volume Pedal, Mint w\/ Box","description":"Up for sale, a Lehle Mono Volume pedal in mint condition, complete with the original box and paperwork. The Lehle Mono 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 Mono 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.\u003cbr\u003e\n\u003cbr\u003e\nA premium Blackmer VCA (Voltage Controlled Amplifier) replaces 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 the pedal to operate more precisely than conventional mechanical potentiometers or optical sensors used by the standard volume pedals. In addition the potentiometer-typical noise and the complicated adjustment are eliminated.\u003cbr\u003e\n\u003cbr\u003e\nOver the entire control range, the Lehle Mono 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.","brand":"Lehle","offers":[{"title":"Default Title","offer_id":49144963498240,"sku":"15.31221","price":209.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/4437\/4714\/files\/medium_a3e7fea5-74db-4524-9281-dd8b5b4555f0.jpg?v=1786128847","url":"https:\/\/mmguitarbar.com\/products\/lehle-mono-volume-pedal-mint-w-box","provider":"Mike \u0026 Mike's Guitar Bar","version":"1.0","type":"link"}
