Stone Deaf PDF-1 Parametric Distortion Filter

Handwired in the UK, the original PDF-1 is a cult classic filter/boost that became a secret weapon for Josh Homme for that signature QOTSA sound. Features gain stage, sweepable frequency knob, and height control to cut or boost, plus a Q switch to flip between wide humps and narrow spikes. Unlike a standard EQ, this one responds like an instrument — great for shaping drive tones or punching through a live mix.

Specifications:

• Parametric distortion filter pedal
• Frequency sweep from bass to high-mid
• Height knob for boost or cut
• Q switch for bandwidth control
• Built-in gain boost
• True bypass switching

Includes original box.
