Earthquaker Devices Blumes Low Signal Shredder Bass Overdrive Pedal

The EarthQuaker Devices Blumes® is a tri-mode all-analogue soft clipping bass overdrive, designed to capture the essence of the classic “screamer” circuit while delivering a bold, full-frequency voice that’s all its own. Based on the award-winning Plumes® Small Signal Shredder, Blumes doubles the gain and deepens the bass response to maintain powerful low-end clarity and punch — perfect for bassists and guitarists seeking rich, dynamic overdrive tones.

With its internal bipolar power providing enhanced headroom and dynamics, Blumes achieves a three-dimensional tone that cuts through the mix while retaining the natural feel of your instrument. From subtle grit to full-blown bass-driven saturation, Blumes pushes your amp over the edge with stunning precision and authority.

Tone and Versatility

At lower gain settings, Blumes delivers the same tight, responsive crunch loved in the original Plumes circuit — but as you push the Gain control beyond noon, the extra headroom and deep bass character transform it into a powerhouse drive pedal that shakes walls and fills rooms.

Blumes features three distinct clipping modes, each offering a different tonal character and response:

• Mode 1 – Symmetrical LED Clipping
  Crunchy, open, and powerful. Offers less compression, more output, and a raw, amp-like response.

• Mode 2 – Clean OpAmp Gain Boost
  Removes clipping diodes entirely for a loud, full-range boost. Ideal as a clean driver or preamp enhancer with maximum headroom.

• Mode 3 – Asymmetrical Silicon Clipping
  Warm, smooth, and compressed with fuzzy edges and clean undertones. Produces a transparent, classic overdrive character with rich harmonic content.

Whether you’re tightening your low end, adding warmth to your clean tone, or crafting earth-shaking overdrive, Blumes adapts effortlessly to your playing style.
