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 de-activation of this match let Galileo’s tremolo effect be very natural without distortion of the input signal.
Galileo is provided with two true-bypass footswitches: GO and TAP.
- 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 desidered 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.
Galileo is provided with five knobs that let you fully control the analogue oscillator and the tremolo effect as desidered.
- SPEED: on manual mode (with SPEED MOD selector on central position) SPEED knob let you manually set the tremolo speed as desidered. NOTE: the max tremolo speed is 1Hertz (1 second period). If TAP speed is active, by manually control SPEED knob the oscillatori s immediatly 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 attach 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 oscillaotor 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.
Galileo pedal is provided with a dedicated led status indication that let the user understand the pedal status. Galileo comes with two leds on top of the footswitches GO and TAP.
- GO LED is blue and has two possible states:
- OFF: the Galileo pedal is OFF and the input signal is bypassed to the output
- ON: the Galileo pedal is active and the output signal is modulated by Galileo’s tremolo oscillator-photodiode
- TAP LED has four possible states. It always blinks at the current oscillator speed, no matter what the GO footswtich is ON or OFF. This let you be always able to monitor the oscillator speed, even when the GO footswitch is OFF and Galileo is in bypass mode. The TAP led blinks on the following four LED status:
- BLU: the tremolo oscillator is running on MANUAL mode: the oscillator speed has not been set by TAP tempo and the speed has been manually set from SPEED knob (this is the default condition at power-on)
- RED: the analogue oscillator’s circuit is attaching to the TAP tempo. When a TAP tempo is inserted with the footswitch, the oscillator needs to analogically match the oscillaotor speed to the new TAP speed: during the attach time the LED blinks red.
- GREEN: when oscillator speed is perfectly matched to the new TAP speed the TAP LED blinks GREEN. On this status you can always check the oscillaor speed and the TAP status, no matter the GO footswitch state is OFF or ON.
- GREEN+RED: Galileo is performing a SPEED MODULATION (details described on next “Selectors” section)
- TAP SPEED: The TAP speed defined by pressing the TAP footswitch is matched with the TAP SPEED selector. It has tree positions: 1x, 2x and 3x. This selector let the oscillator period that has been set with the TAP footswitch be modified as follow:
- 1x: the oscillator has a speed identical to the inserted TAP footswitch synch
- 2x: the oscillator has a speed twice the inserted TAP footswitch synch
- 3x: the oscillator has a speed three times the inserted TAP footswitch synch
Once the TAP period is attached by the oscillator, it is possible to set the TAP speed selector as desidered, without a new TAP footswitch speed set: the oscillator and the TAP SELECTOR will always be attached to the last valid TAP speed.
Example: set the TAP selector to 1x. With the TAP footswitch set the oscillator to 2 Hertz speed (this means that the TAP footswitch has been pressed at least twice with 500ms interval to each TAP press). The oscillator will attach to a 2 Herts speed. By selecting 2x position of TAP SPEED selector the oscillator will automatically attach to 4 Herts speed. By selecting 3x position the oscillator will attach to a 6 Hertz speed. It is possible to set the TAP speed with the TAP selector on either 1x, 2x or 3x position: the oscillator will automatically set the tremolo speed multiplying the TAP speed by the TAP selector choice.
- SPEED MOD: controls the speed modulation of the tremolo. When a speed tremolo has been set, this control let it be possible to automatically modify the tremolo speed. SPEED MODULATION selector has tree positions:
- Central: no speed modulation is performed. The tremolo speed will be set by both TAP or manually with SPEED knob and the user has full control on the speed set.
- Left: is the SHIFT speed modulation. By setting the SPEED MOD on the SHIFT position the speed of the oscillator will automatically start to be shifted to twice and back to original speed. When SHIFT speed modulation is on, the SPEED knob sets how many ripetitions will decide the speed shif. With SPEED knob set to min, after each ripetition of the oscillator the speed will be duplicated and set back to original SPEED. With SPEED knob set to max, the speed shift will be performed after 8 ripetitions. On mid positions of SPEED the shift repetitions will be linearlly set on the range of 1 to 8 ripetitions (on mid position the ripetitions will be 4)
- Right: is the UP-DOWN speed modulation. The speed will be increased and decremented following a sine wave. On this SPEED MOD selection the SPEED knob sets how fast the UP-DOWN modulation is going to modify the tremolo SPEED.
NOTE: during manual or TAP speed configuration always keep SPEED MOD selector to central position. Only activate SPEED MOD when TAP is attached (TAP LED blinking GREEN).
