TH-20 (Thriller)

Effect Information

From Pearl (80s advertising):

  • Pearl’s Thriller, TH-20, is a new and exciting effect which creates a clear and brillant sound by using a low-cut filter and a multi-peak circuit to boost the peaks of the six most effective and audible points of the high frequency range.

Controls:

  • 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.

“This is a pretty sweet effect — a bit like a wah pedal parked in one spot, only with a lot more control over the ultimate shape of the sound.”

“Exciter pedal from the Pearl Sound Spice Series. This pedal is used to create a clear and brilliant sound by using a low-cut filter and a multipeak circuit to boost the peaks of the six most effective and audible points of the high frequency range. Manufactured between 1984 and 1986 in Japan.”

“In reality, the TH-20 is a mess of a pedal that really f**** up your sound and does nothing musical. It creates strange humps on frequencies and is more of a noisemaker than anything.”
