A Wicker switch opens three high-frequency filters for brighter, more defined sustain, and a Tone switch bypasses the tone circuit entirely for a raw, high-output drive with uncolored gain. Controls include Sustain, Tone, and Volume knobs. True bypass switching preserves the bypassed signal path. The pedal runs on a 9V battery or a center-negative 9VDC supply rated at 50mA (EHX recommends the US96DC-200BI). A 9V battery is included. The die-cast metal chassis is built for pedalboard use.\u003c\/p\u003e","brand":"Electro-Harmonix","offers":[{"title":"Default Title","offer_id":51242340548854,"sku":null,"price":39.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/2882\/7894\/files\/IMG_6638.jpg?v=1783727545","url":"https:\/\/envoy-music.myshopify.com\/products\/ca-electro-harmonix-electro-harmonix-headphone-amp-used-73c353540e","provider":"Envoy Music","version":"1.0","type":"link"}
