{"type":"firestarter.listing","listing":{"id":"lst_olQ35A2D","product_name":"Fundamental Series Phaser","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 Phaser\nThe Fundamental Phaser is a versatile digital emulation of a classic phaser. With three types of Phaser algorithms to select from, you can get sounds ranging from light tonal modulation to a highly modulated and resonant phaser.\nRate:  Controls the rate of the modulated LFO. A higher rate will produce a faster and more pronounced pitch modulation, while a lower rate will produce a slower and more subtle effect.\nFeedback: Control the amount of affected signal sent back into the feedback loop, more feedback creates more resonance. \nDepth: Controls the depth of the modulated LFO. This affects the amount of pitch modulation applied to the affected signal. \nSlide Switch – The slide switch allows you to change between three distinct flavors of the pedal. \n\nLight – A scaled-back phaser that slightly modulates your signal.\n\n\nMedium – Emulates a classic warm analog phaser.\n\n\nHeavy – Multi-voiced phaser with lots of experimental sounds. \n\n All Walrus Audio Products are covered by our limited lifetime warranty.
