{"type":"firestarter.listing","listing":{"id":"lst_a58ex6yo","product_name":"Fundamental Series Distortion","category":"Pedal","description":"For the Fundamental Series, we challenged ourselves to design a set of pedals with the tonal integrity that’s required to live on a professional’s pedalboard, but with simplified controls friendly enough for even the newest effect pedal users. Each Fundamental pedal has three faders for tweaking the sound and a three-way switch for changing pedal modes. The result is a line of pedals that will keep you covered from your first band practice all the way to a sold-out arena. Designed and assembled at Walrus Audio headquarters in OKC, OK. \nFundamental Distortion\nThe Fundamental Distortion is a three-mode distortion. It covers a wide range of sounds from dark and doom through sharp cutting leads.\nGain – The Gain slider sets the amount of gain applied to your guitar signal passing through the distortion circuit.\nTone – The Tone slider controls the signal's frequency response after distortion. Left of center cuts highs and right of center boosts highs.\nVolume – The Volume slider sets the overall output volume of the pedal.\nSlide Switch – The slide switch allows you to change between three distinct flavors of the pedal. Each position has different clipping modes or tone profiles.\n\nDark - Asymmetric silicon clipping with an added high-frequency cut. Think dark and dynamic.\n\n\nSi - Classic silicon hard clipping diodes. Things get compressed and crunchy.\n\n\nLED - LED hard clipping diodes. A dynamic and crunchy sound. \n\nNote: The LED clipping mode will be louder due to the nature of the LEDs, so use your volume slider to compensate!\n All Walrus Audio Products are covered by our limited lifetime warranty.
