Seppuku Effects Digital Pitch Modulator 2 (DPM-2)

Seppuku Effects Digital Pitch Modulator 2 (DPM-2)


The DPM-2 is actually the second version of Seppuku FX's digital pitch modulator. 

Version 2 boasts of a smoother synth-like tone. This effects pedal uses an 8-bit digital chip to create effects such as octave up, octave down, ring modulation, fifth note doubling, arpeggio, and what Seppuku FX describes as bit crusher sounds for your guitar, keyboards, or any other instrument that you decide to plug into it. As experimentation is at the essence of Seppuku FX releases, the DPM-2 is no different. 

Controls come in the form of three pots for master volume, analog/digital blend (controls mix between modulated sounds and analog fuzz), and oscillator frequency (controls the pitch of the ring modulator). The oscillator frequency control pot can lower the fidelity of the sound by turning it down and can also control arpeggio effect/pitch jump sound speed when the pointer is turned upwards. The DPM-2 also has toggle switches which allow you to control the pitch wherein various settings give you a variety of pitch effects. As there are no labels on the toggle switches, the DPM-2 is bound to give you a lot of surprises as you play around various toggle switch combinations. 


  • Blend: mixes between modulated sounds and analog fuzz  
  • Master Volume: controls two filters by 1 knob.  
  • Oscillator Frequency: controls the pitch of the ring modulator
