Fat & creamy distortion just like the original JAM Rattler, with enhanced versatility and tonal options. Incorporating a custom design op-amp that maintains all the beloved characteristics of the original but adds a custom-voiced mid boost and introduces a second clipping option.

Key Features

  • Mid Boost Footswitch – Use the second footswitch to engage a mid-boost just before the Rattler. This adds a new dimension to the tone and enhances it!
  • Choose How you Clip – Switch between Asymmetrical and Symmetrical clipping to shape your tone your way.
  • Internal Trimmer – Have full control over the boost and how it behaves.
  • Internal Dip Switch – This applies a low cut to the boost side of the pedal which reduces low end and tightens up the sound.

JAM Pedals have always prided themselves on faithfully recreating early 80s distortion pedals.

What is the Op-amp?

The LM308 chips are long discontinued and hard to find, so Jam Pedals took on the challenge of developing a custom op-amp that preserves the open, dynamic tube amp feel which made the original JAM Rattler so popular.

  • Works with 9V DC adaptor (tip-negative)
  • Power consumption: 95 mA

Overdrive Pedals

Overdrive uses soft or moderate clipping to add harmonics and compression while retaining more of the original note shape than heavy distortion. Some circuits emphasise the midrange and trim bass before clipping; others remain broad, transparent or amplifier-like. Gain, clipping arrangement, headroom and tone filtering decide whether it supplies a light edge, a saturated drive sound or extra push into another gain stage.

Distortion

Clips the waveform firmly and adds a dense series of harmonics with compression and sustain. The clipping devices, gain stages and tone filters determine whether the result is tight, smooth, mid-focused, scooped, grainy or deliberately abrasive.

True Bypass

Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
