U.S. guitar effects pedal builder Mojo Hand FX has teamed up with the non-profit program Girls Rock! Grand Rapids (GR!GR) of Grandville Avenue Arts & Humanities to create a limited edition overdrive called the GRRRocker.

Deriving its moniker from the Riot Grrrl movement, all profits from the GRRRocker go directly towards resourcing Girls Rock! camps in Grand Rapids and partner camps worldwide.

A press release says the overall idea, artwork and color scheme for the GRRRocker was created by GR!GR campers during camp week 2019. Volunteers then took the idea to Mojo Hand FX who later developed this one-of-a-kind stompbox.

For every four GRRRocker pedals sold, one will be donated to a Girls Rock! camp where girls and gender-expansive youth learn to write, perform and record music.

Retailing for $150, the flexible GRRRocker is suitable for bass players and guitarists of any level and offers a smooth, tube amp-like overdrive tone.

Here’s a rundown of the GRRRocker specs:

  • Controls for Volume, Tone, and Gain
  • Pushbutton selection for clipping options: Up = Crunch (hard clipping) / Down = Overdrive (soft clipping)
  • True bypass
  • Precision control for distortion (internal trim pot accessed via back panel)
  • 9V standard center negative power supply (not included), no battery provision
  • Durable sparkling white matte powder coat finish with hand-drawn artwork
  • Current draw ~15 mA
  • Made in the U.S.A.
  • Lifetime warranty
  • Dimensions: 4.42" x 2.39" x 1.21" (LxWxH)
