{"type":"firestarter.listing","listing":{"id":"lst_Yn7Tfr1n","product_name":"Fundamental Series Drive","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 Drive\nThe Fundamental Drive is a versatile overdrive that allows for a wide range of tones thanks to its three-mode switch. This is the perfect tool at the front of your chain to set the tone for your whole rig.\nGain – The Gain slider sets the amount of gain applied to your guitar signal passing through the overdrive circuit.\nTone – The Tone slider controls the amount of high-frequency level reduction.\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\nSmooth - A classic soft-clipping silicon overdrive. Clean and smooth.\n\n\nCrunch - Silicon soft clipping with added hard clipping silicon diodes and a slight low-end boost. Crunchy and edgy.\n\n\nBright - Silicon soft and hard clipping from the Crunch mode with a pre-clipping low-end cut. Bright and glassy.\n\n All Walrus Audio Products are covered by our limited lifetime warranty.
