{"type":"firestarter.listing","listing":{"id":"lst_r0X9wZVM","product_name":"Fundamental Series Fuzz - BLEMISHED","category":"Pedal","description":"*Blemish is cosmetic only such as scratches or dents in the finish of the pedal.*\nFor 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 Fuzz\nThe Fundamental Fuzz is a three-mode aggressive fuzz pedal with a wide tonal range. It can live anywhere in your chain: hit it with your favorite overdrive or push it into another crazy distortion.\nGain – The Gain slider sets the amount of gain applied to your guitar signal passing through the fuzz circuit.\nTone – The Tone slider controls the signal's frequency response after distortion. Left of center cuts highs and right of center cuts lows.\nVolume – The Volume slider sets the overall output volume of the pedal.\nSlide Switch – The slide switch allows you to change between three distinct different flavors of the pedal. Each position has different clipping modes or tone profiles.\n\nGate - Lowers bias voltage in the main fuzz section, creating a gated and starved sound. Note: Changing the bias lowers the overall level of the pedal compared to the other modes. With plenty of gain on tap, use the Volume slider to compensate.     \n\n\nClassic - Screaming fuzz with an iconic mid scoop, give you a compressed and crunchy sound.\n\n\nMid+ -  Adds mid boost to flatten out the tone stage, resulting in a compressed but rich and full sound.\n","images":["https://cdn.shopify.com/s/files/1/0906/8480/files/Front_d2ac2f70-721c-42d1-9fff-9ec906c48e54.jpg?v=1755546545","https://cdn.shopify.com/s/files/1/0906/8480/files/Left_a2c17c6c-750a-4745-9858-e531d6c2c797.jpg?v=1755546546","https://cdn.shopify.com/s/files/1/0906/8480/files/Right_409dc6d3-eb35-44dc-96b3-bd3e6444e658.jpg?v=1755546545"],"price":84.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:57:20.131Z"},"share_url":"https://firestarter.network/l/lst_r0X9wZVM","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
