Pearl TH-20 Thriller


  • Frequency
    Adjusts the point where the frequency is cut-off by the low-cut filter. Turning clockwise raises the frequency's cut-off point (600Hz-7kHz).
  • Balance (Direct-Filter)
    Mixes the direct sound and the low-cut sound. Turning clockwise from zero increases the ratio of low-cut sound to the direct sound. Turning counterclockwise from zero increases the ratio of the direct sound to the low-cut sound.
  • Color
    Boosts the levels around the cut-off point of the low-cut filter. Turning clockwise increases the amount of boost.
  • Multipeak
    Boosts the frequency of the six points of the high frequency range. Turning clockwise raises the peak level.
