3.1 ປຸ່ມຄວບຄຸມ

• ຜະສົມຜະສານ: 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.
• ລະດັບ: ກຳນົດປະລິມານຜົນຜະລິດໂດຍລວມຂອງ pedal.
• ຂັບ: Controls the amount of gain in the overdriven signal.
• ຕ່ຳ: Adjusts the level of the low frequencies.
• Lo Mids: Adjusts the level of the low-mid frequencies. The center frequency can be switched between 500 Hz and 1 kHz.
• ສະບາຍດີ Mids: Adjusts the level of the high-mid frequencies. The center frequency can be switched between 1.5 kHz and 3 kHz.
• ສຽງສູງ: Adjusts the level of the high frequencies.

3.2 ສະວິດ

• ສະຫຼັບການໂຈມຕີ: Modifies the treble content of the overdriven signal. Options are Boost, Flat, and Cut.
• Grunt Switch: 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).
• Hi Mids Switch: Selects the center frequency for the Hi Mids knob (1.5 kHz or 3 kHz).
• ສະວິດຍົກພື້ນ: Disconnects the ground from the XLR output to help eliminate hum or ground loops when connected to external equipment.
