Dophix Galileo Optical Tremolo Effects Pedal Description Galileo is not an effect like the others: to make a pedal by hand, days and days of work are necessary. Galileo Galilei was an Italian physicist, astronomer, philosopher, mathematician and academic, considered the father of modern science. Dophix was inspired by this great man because they want to bring a revolution in the sound dimension! Galileo is a full analogue optical tremolo with versatile regulations, tap tempo and modulation controls. The heart of Galileo is an internal analogue oscillator that controls an high quality photodiode producing the tremolo: the activation and deactivation of this match let Galileo’s tremolo effect be very natural without distortion of the input signal. Features With GO footswitch Galileo activate the tremolo effect and the output signal is modulated by the photodiode and the oscillator. When GO is on, a blue led lights on as a feedback. When GO footswitch is OFF the input is bypassed, so that the input signal is directly connected with the output jack.With TAP footswitch it is possible to set the tremolo oscillator period as desired by pressing TAP. Each TAP trigger set the start/stop of the oscillator period. A minimum of two tap triggers are required in order to set the desidered TAP period. No upper TAP triggers limits have to be respected. NOTE: the max oscillator period is 1 second: in case a longer TAP is requested the internal circuit will limit the TAP period to 1 sec.SPEED: on manual mode (with SPEED MOD selector on central position) SPEED knob lets you manually set the tremolo speed as desired. NOTE: the max tremolo speed is 1Hertz (1 second period). If TAP speed is active, by manually control SPEED knob the oscillator is immediately controlled in manual mode, with speed set by the SPEED knob.DEPTH: controls the amount of tremolo effect added to the input signal. With DEPTH set to min the input signal has no tremolo effect. With DEPTH set to max the tremolo effect if full and when the tremolo photodiode is off no signal will be to the output. In mid positions of DEPTH it is possible to adjust the mix of the input signal with the full tremolo modulation.SMOOTH: sets how strong is the impact of the analogue oscillator into the photodiode conduction, responsable of the tremolo effect.ATTACK: set the attack of the tremolo compared to the oscillator settings. ATTACK let you set when the photodiode will be activated concerning the oscillator signal amplitude.SYM: the photodiode is turned on/ off when the oscillator sinusoidal signal is at the peak / bottom of the amplitude. SYM sets the relation between the oscillator waveform and the photodiode conduction by modifying the peak/bottom position of the oscillator.Made in Italy Attributes Color (X): SilverEffect Type (X): TremoloOutput (X): 1/4"Input (X): 1/4"True Bypass (X): YesStereo/Mono (X): MonoModel Name (X): Galileo Optical TremoloVideo Link (X): https://youtu.be/j9x7y30qRyE
