Description
Add something truly unique to your pedalboard with the PLASMA Pedal from Gamechanger Audio, a distortion pedal that let's you literally play a bolt of lightning. By converting your input signal into high-voltage electric discharges in a xenon tube, you can achieve distinctively clipped audio quite unlike any other distortion pedal.The distortion effect is sharp, sizzling, clear, and highly responsive to your picking style, with a natural noise-gating feature via the Blend knob that can create strong contrasts between staccato notes or hide unwanted noise and hum. Two EQ controls (High Freq and Low Freq) provide an extremely wide EQ range, ideal for bass guitar, thanks to the unique method of distortion, and can be applied to the wet or dry signals by selecting a dedicated rear-panel switch. Excellent harmonic transparency for even the most complex chords allows PLASMA Pedal to add something special to not only guitar and bass, but also synthesizers, drum machines, vocals, and more.How It Works Instead of traditional LED circuits, transistors, or vacuum tubes, the PLASMA pedal produces distortion by converting your instrument's signal into a series of electrical impulses (via pulse-amplitude modulation) that are sent to a step-up fly-back transformer. The transformer amplifies these bursts to the order of thousands of volts and then discharges the current into a special xenon gas-filled glass tube (viewable on pedal itself).The xenon gas is ionized and acts as a conductor, carrying the bright discharges from one electrode to the other, while a special antenna acts as a rectifier, picking up the electromagnetic waves of the discharge and reforming them back into audio signals. This process ultimately modulates and alters the audio signal in a unique and distinctive manner, with a signature sound character unlike any other distortion method.A Distinctive, Singular Analog Distortion Sound The harmonic artifacts, created as a byproduct of the high-voltage discharge are uncommon in traditional signal amplification, and therefore plasma distortion is unlike anything you have heard before. The PLASMA Pedal produces a large amount of nonlinear harmonic saturation that causes extremely rich and responsive attacks and brings out screeching sharp overtones and harmonics.The way the plasma tube reacts with different instruments and sound sources is quite unique. The scope of distortion intensity goes from sputtery broken sounds to full saturation and sustain all the way to totally oversaturated tones. The level of distortion is controlled with the Blend and Voltage knobs.Unusual Harmonic Saturation When an audio signal is driven by a step-up transformer, all the harmonics and overtones that are present in the original signal become very pronounced. There is also a certain amount of noise pollution that is created by the transformer and gas-tube system. This sound can be described as a crackling or buzzing sound, and it adds an electric quality to the distortion tone.Knobs and Controls Voltage: lets you adjust the amount of current sent to the xenon tube, increasing or decreasing the theshold necessary for achieving a discharge in the tubeVolume: standard master volume control, with 12 o'clock offering unity gain, though it may vary depending on EQ settingsBlend: balance between the wet and dry signals, with fully clockwise providing a wet only signal, and fully counterclockwise providing an entirely dry signalLow Freq: controls low frequency content, offering 9 dB of adjustment at 600 HzHigh Freq: adjusts 10 dB of high-frequency content at 1.5 kHzNatural Noise Gate and Clean Gate As soon as you stop playing, the electrical discharge within the gas-filled tube is interrupted, and the pedal will not produce any output signal at all. This feature allows you to achieve extreme contrasts between individual notes, by eliminating all of the in-between noises created by the instrument's pick-ups or by humming strings. The gating effect can also be
