4. Setup
- Konnessjoni tal-Enerġija: Connect a standard 9VDC center-negative power supply (not included) to the 9VDC input jack on the pedal. Ensure the power supply meets the specified voltage and polarity requirements to prevent damage.
- Konnessjoni tal-Input: Connect your guitar or the output of your last pedal in the signal chain to the 'IN' jack on the pedal using a standard 1/4-inch instrument cable.
- Konnessjoni tal-Output: Connect the 'OUT' jack of the pedal to your amplifier's input or the input of the next pedal in your signal chain using a standard 1/4-inch instrument cable.
- Pedala tal-Espressjoni (Mhux obbligatorja): If using an expression pedal, connect it to the 'EXP' jack using a TRS cable.
- Settings Inizjali: Before powering on, set all knobs to their middle positions and ensure both footswitches are disengaged (LEDs off).
5. Operazzjoni
5.1 Fuzz Section
- Engaging Fuzz: Press the FUZZ footswitch to activate the fuzz effect. The corresponding LED will illuminate.
- FUZZ Knob: Adjusts the amount of fuzz gain. Higher settings produce more saturation and sustain.
- Buttuna tal-FILTRU: Shapes the tone of the fuzz. Experiment with this knob to find your desired frequency response, from darker to brighter tones.
- FUZZ Toggle Switch: Selects between three distinct fuzz voicings:
- ĊATT: A balanced, full-range fuzz tone.
- SCOOP: Scoops the mid-range frequencies, often used for a classic Big Muff-style sound.
- SĦIĦA: Boosts the low-end and overall output for a thicker, more powerful fuzz.
- FUZZ Level Knob: Controls the overall output volume of the fuzz effect.
5.2 Modulation and Delay Section
- Engaging Mod/Delay: Press the MOD footswitch to activate the modulation or delay effect. The corresponding LED will illuminate.
- DELAY/MOD Switch: Toggles between Delay and Modulation modes.
- MOD Level Knob: Controls the overall output volume of the modulation or delay effect.
Modalità Dewmien:
- BLEND/TAPE HEAD Knob: In Delay mode, this knob selects one of 12 multi-head tape delay programs. Each program offers a unique rhythmic pattern of repeats. Refer to the Tape Head Matrix for details.
- DEPTH/TIME Knob: Adjusts the delay time, from short slap-back echoes to long, ambient repeats.
- RATE/FDBK Knob: Controls the feedback (number of repeats) of the delay. Higher settings result in more repeats.

Modalità ta' Modulazzjoni:
- BLEND/TAPE HEAD Knob: In Modulation mode, this knob blends the dry signal with the wet (effected) signal.
- DEPTH/TIME Knob: Adjusts the intensity or depth of the selected modulation effect.
- RATE/FDBK Knob: Jikkontrolla l-veloċità jew ir-rata tal-effett ta' modulazzjoni magħżul.
- Tipi ta' Modulazzjoni: The pedal offers Flanger, Rotary Speaker Cabinet, U-Vibe, and Phaser. The specific modulation type is selected via internal settings or a combination of knob positions (refer to the full product manual for advanced details if available).
5.3 Expression Pedal Functionality
When an expression pedal is connected to the EXP jack, it can be assigned to control various parameters within the Modulation or Delay section, such as Delay Time, Modulation Rate, or Blend. Consult the full product manual for specific assignments and calibration instructions.
5.4 Effect Order Switch
The ORDER switch allows you to change the internal signal flow of the Fuzz and Modulation/Delay sections. This significantly impacts the overall tone and interaction between the effects:
- Fuzz First: The fuzz effect processes the signal before the modulation/delay. This is a common setup for classic fuzz tones with trailing effects.
- Mod/Delay First: The modulation/delay effect processes the signal before the fuzz. This can lead to unique and experimental sounds, where the fuzz acts on the modulated or delayed signal.
6. Manutenzjoni
- Tindif: Uża drapp artab u niexef biex tnaddaf il-barra tal-pedala. Evita prodotti tat-tindif jew solventi li joborxu.
- Ħażna: Aħżen il-pedala f'post frisk u niexef 'il bogħod mix-xemx diretta u minn temperaturi estremi.
- Qawwa: Dejjem skonnettja l-provvista tal-enerġija meta l-pedala ma tkunx qed tintuża għal perjodi twal.
- Konnessjonijiet: Iċċekkja perjodikament il-konnessjonijiet tal-kejbil kollha għal xedd u kedd. Kun żgur li l-ġakkijiet huma ħielsa mit-trab u l-fdalijiet.
7 Issolvi l-problemi
- Ebda Ħsejjes:
- Iċċekkja l-konnessjonijiet tal-kejbil kollha (il-kitarra għall-IN, l-OUT għall- amp).
- Kun żgur li l-provvista tal-enerġija hija konnessa sew u qed taħdem.
- Verify that the pedal is engaged (LEDs illuminated for active effects).
- Check the volume knobs on the pedal, guitar, and ampaktar ħaj.
- Fuzz Not Engaging/Working:
- Ensure the FUZZ footswitch is pressed and its LED is on.
- Check the FUZZ knob setting; ensure it's not at minimum.
- Test with different cables and power supply.
- If the MOD section works but Fuzz does not, there might be an internal issue requiring professional service.
- Storbju/Ħoss eċċessiv:
- Ensure you are using a regulated 9VDC center-negative power supply. Unregulated or incorrect power supplies can cause noise.
- Iċċekkja għal ground loops fis-setup tiegħek.
- Mexxi l-pedala 'l bogħod mit-transformers tal-enerġija jew minn sorsi oħra ta' interferenza elettromanjetika.
- Ipprova kejbils differenti.
- Effects Not Modulating/Delaying Correctly:
- Ensure the MOD footswitch is pressed and its LED is on.
- Verify the DELAY/MOD switch is in the desired position.
- Adjust the DEPTH/TIME and RATE/FDBK knobs.
- For delay, ensure the BLEND/TAPE HEAD knob is set to an active program.
