Product Description for the Dunlop JP95 John Petrucci Signature Wah

The JP95 John Petrucci Signature Cry Baby Wah is the result of the legendary prog metal shredder's years-long quest to hone his perfect wah tone. For years, John used the Cry Baby Rack Wah system to tweak and fine-tune its numerous parameters until he found the sound that perfectly represents all the expression and intensity he needs. Recently, he and Dream Theater engineer Richard Chycki worked with the Cry Baby design team to replicate and further fine-tune that sound with a single pedal. This is a wah that, as John puts it, sounds huge and badass like an angry, screaming monster with the ultimate expressive range-it's perfect for shaping single notes or manipulating growling, heavy chords.

Factory set to John's personal settings, the JP95 features all the controls he used to find his Cry Baby voice: Volume to add gain, Q to shape the width of the effect, and a 6-band EQ to shape the tone of the wah sound, from 100Hz to 3.2KHz. Want to fine-tune the sound to your own preference? Just take off the bottom plate and tweak away.

The John Petrucci Signature Cry Baby Wah comes in a sturdy, road-ready housing with custom smoked chrome finish and JP shield logo tread.



The John Petrucci Signature Cry Baby Wah is powered by one 9-volt battery (accessed via bottom of pedal), an AC adapter such as the Dunlop ECB003/ECB003EU, or the DC Brick and Iso-Brick power supplies.

Internal Controls

  • Q ADJ trimpot adjusts width of JP95’s bandpass
  • VOLUME trimpot sets overall effect volume
  • EQ trimpots boost or cut indicated frequency (100Hz–3.2Khz)

Setup Instructions

  • Run an instrument cable from your guitar to the JP95’s INSTRUMENT jack and another instrument cable from
  • the JP95’s AMPLIFIER jack to your amplifier’s input.
  • To turn the pedal on/off, push the toe of the pedal down until you feel a “click.”
  • The JP95 ships with John Petrucci’s control settings by default (see JOHN PETRUCCI’S SETTINGS). Use a trimpot
  • adjustment tool to change the settings to your own preference.
  • Rotate VOLUME control clockwise to increase effect volume or counterclockwise to decrease it.
  • Rotate Q ADJ control clockwise for a narrower bandpass to emphasize higher end harmonics or counterclockwise for a wider bandpass that emphasizes lower end harmonics.
  • The six internal EQ controls—labeled from 100Hz to 3.2Khz—can be used to boost or cut the indicated frequency by +/-18 dBV. Rotate clockwise to boost or counterclockwise to cut.
  • Rock your foot back and forth on the pedal to hear the vocal, expressive tones that the Cry Baby Wah is famous for.
  • Note: Internal TEST/NORM switch is for production testing only. Always leave it set to the NORM position for full
  • functionality of all controls.
