3.1 ручки управления
- Состав: Mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the volume of the overdriven signal is controlled by the Drive knob, allowing for fine-tuning of the blend ratio.
- Уровень: Устанавливает общий уровень громкости педали.
- Водить машину: Controls the amount of gain in the overdriven signal.
- Низкий: Adjusts the level of the low frequencies.
- Ло средние частоты: Adjusts the level of the low-mid frequencies. The center frequency can be switched between 500 Hz and 1 kHz.
- Привет средние частоты: Adjusts the level of the high-mid frequencies. The center frequency can be switched between 1.5 kHz and 3 kHz.
- Высокие частоты: Adjusts the level of the high frequencies.
3.2 Переключатели
- Переключатель атаки: Modifies the treble content of the overdriven signal. Options are Boost, Flat, and Cut.
- Переключатель хрюканья: Modifies the low-end content of the overdriven signal. Options are Thin, Raw, and Fat.
- Lo Mids Switch: Selects the center frequency for the Lo Mids knob (500 Hz or 1 kHz).
- Привет, переключатель средних частот: Selects the center frequency for the Hi Mids knob (1.5 kHz or 3 kHz).
- Переключатель наземного подъема: Disconnects the ground from the XLR output to help eliminate hum or ground loops when connected to external equipment.
3.3 Связи

- Используйте Смешивать knob to mix the clean signal with the overdriven signal. This allows you to retain clarity and low-end presence while adding grit.
- Экспериментируйте с Атака и Грунт switches to fine-tune the treble and bass characteristics of the overdriven tone.
- Utilize the 4-band EQ to sculpt your overall tone. The Lo Mids и Привет средние частоты switches allow you to select different frequency centers for precise control.
- Отрегулируйте Уровень knob to match the output volume with your bypassed signal or to boost your signal for solos.
6. Техническое обслуживание
- Поддерживайте чистоту педали, протирая её мягкой сухой тканью. Избегайте использования абразивных чистящих средств и растворителей.
- Protect the pedal from extreme temperatures, moisture, and direct sunlight.
- Убедитесь, что все кабели находятся в исправном состоянии и правильно подключены, чтобы предотвратить потерю сигнала или его повреждение.

7. Поиск Неисправностей
| Проблема | Возможная причина | Решение |
|---|---|---|
| Нет звука | Incorrect power supply; cables not connected properly; pedal bypassed. | Verify 9V DC center-negative power supply is connected. Check all input/output cables. Ensure pedal is engaged (LED illuminated). |
| Чрезмерный гул или шум | Ground loop; faulty cables; interference from other equipment. | Привлекайте Подъем на землю switch on the XLR output. Try different cables. Ensure power supply is isolated and free from noise. Move pedal away from power transformers or other noisy electronics. |
| Weak or distorted signal (unintended) | Неправильный коэффициент усиленияtaging; faulty instrument cable. | Регулировать Уровень и Водить машину knobs. Test with a different instrument cable. |
