Decadent saturated 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 now has increased headroom.

Whether you are rocking modern or vintage rigs, this rather devious snake will rattle your audience off their feet.

Key Features

  • Dynamic Tone – Pure dynamic overdrive with tube-amp feel just like the original JAM Rattler, but with more headroom!
  • Dry/Wet Mix – Blend your clean and distorted signals for the perfect ratio of grit and articulation.
  • High-Gain Footswitch – Use the second footswitch to engage a higher gain stage for bursts of increased saturation.

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.

Specifications

  • True Bypass
  • Works with 9V DC adaptor (tip-negative)
  • Power consumption: 40 mA
  • Dimensions (including jacks, pots, etc.): 7.5 x 12 x 5.6 cm / 2.9 x 4.7 x 2.2 inches
  • Input impedance: 500k
  • Output impedance: <10k

Check each model for its exact circuit or processing platform, controls, power requirements and connections, particularly where the catalogue includes both pedals and supporting gear.

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.

Bass

Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.

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.
