- 운전하다: Controls the amount of gain in the overdriven signal.
- 낮은: Adjusts the level of the low frequencies.
- 낮은 중간: Adjusts the level of the low-mid frequencies. The center frequency can be switched between 500 Hz and 1 kHz.
- 안녕하세요 미드: Adjusts the level of the high-mid frequencies. The center frequency can be switched between 1.5 kHz and 3 kHz.
- 고음부: Adjusts the level of the high frequencies.
