Allow JustPedals to introduce the JAM Pedals Bass Rattler MK2 Overdrive-Distortion Pedal

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.

  • 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

Distortion

Distortion pedals take your clean guitar signal and transform it into something bigger, bolder, and full of attitude. By clipping the waveform, they add sustain, bite, and aggression, creating that thick, compressed tone that’s powered rock music for decades. From the growling crunch of classic hard rock to the tight, saturated roar of modern metal, distortion is all about energy and presence. It gives every note weight and authority, pushing your amp to its limits and beyond.

There are countless flavours of distortion, each with its own texture and edge. Some sound smooth and creamy, others raw and gnarly like tearing fabric. It’s the sonic equivalent of turning up the heat until the sound cooks — rich, sizzling, and perfectly seasoned to taste. Whether used for rhythm muscle or soaring leads, a good distortion pedal doesn’t just add volume; it adds personality, grit, and that unmistakable sense of power under your fingers.

Overdrive

Like a golden layer of melted cheese — warm, gooey, and just put it all over. It adds just the right amount of richness and grit, turning a clean signal into something smooth and savoury. Designed to mimic the natural breakup of a tube amp pushed to its sweet spot, overdrive delivers the flavour of classic rock and blues in every bite. From creamy mid-gain warmth to crisp edge-of-breakup sparkle, it’s the comfort food of guitar tone — simple, satisfying, and endlessly versatile. Whether it’s a mild crunch or a full-bodied roar, overdrive is where good taste begins.
