Well, it’s that time again, time to journey down the sonic rabbit hole that comes from all creations made by Pladask Elektrisk. Today’s wild machine, the Feber Amplitude/Phase Modulator, is an exploration of the intersection of single sideband modulation, ring modulation, phasing and tremolo. Blips, beeps, sweeps, creeps and more pour our of this gorgeous effect, blowing all you thought you knew about sound right out of the water…
Feber combines a ring modulator pair, a Hilbert transform approximation, feedback and a random value sample/hold generator into a feature rich tool for exploring amplitude- and phase-based modulation at both high and low frequencies. This pedal has a lot of sensitive controls, which interact with each other to create a near-endless field of exploration and wonder. We’d write ’em all down here for you, but they’re laid out in detail in the demo video below, which you know you’re gonna watch anyway, right?
From Pladask Elektrisk: “The bell-like, inharmonic timbre associated with ring modulation is due to linear frequency shifting. When ring modulation is applied to a signal its frequency content is shifted linearly into an upper and lower sideband. While ring modulation makes an upper and lower sideband, singe sideband modulation/linear pitch shifting yields either the upper or lower. Our human perception favors logarithmic pitch intervals for melodic harmony. Combine 400 and 800 Hz and you have a perfect octave interval. Introduce a 100 Hz linear frequency shift and the octave interval is turned into a 500 – 900 Hz inharmony. Fun, destructive stuff.”
It’s hard to put into words and accurately describe basically ALL of the effects we’ve had the pleasure to check out from Pladask Elektrisk, and that is precisely why they’re one of our all-time favorite pedal companies. The Feber Amplitude/Phase Modulator is one of the most intriguing yet, with new auditory inflections waiting around every curve and corner. Thanks so much to Knut and Pladask Elektrisk for sending this one over – at just under 12 minutes, our demo is lengthy, but once you settle in, all your questions will be (hopefully) answered. Enjoy!
