Earthquaker Devices Blumes - Low Signal Shredder Bass Overdrive

Blumes™ Low Signal Shredder is the first EarthQuaker Device created specifically for bass players! The industrious Blumes™ is also the perfect pedal for guitarists’ deep overdrive needs, especially for the drop-tuned masters.  

While embodying most of the kick ass characteristics and features of the Plumes™, we went ahead and modified this circuit with double the gain and a deeper bass response to retain all the low end. Lower gain settings provide all of the crunchy tone found in the Plumes™, but once you get above noon on the gain control, that’s where the similarities stop. Now you’re in bass country, baby!  

This all-analog tri-mode overdrive with soft clipping carries the torch of the classic screamer circuit but has a voice all its own. And thanks to its +/- power supply it utilizes bipolar power, which offers more dynamics, clarity, and all of the headroom one could ever desire. The end result is a more three-dimensional tone with added clarity that really pushes a nice tube amp over the edge.

And much like the Plumes™, this pedal offers three different clipping options to meet all those low end face melting needs.

Mode 1 is symmetrical LED clipping that utilizes a pair of light emitting diodes. This is the crunchiest setting the Blumes has to offer. This signal is less compressed and way more open with tons of output.

Mode 2 is a clean pure OpAmp gain boost mode. This eliminates the soft clipping diodes altogether, resulting in straight OpAmp drive. This will be the loudest output with the fullest frequency response, which can be used as a clean boost from 0-11 o’clock.

Mode 3 is an asymmetrical silicon diode arrangement similar to the stock screamer but with more output and clean clarity, which provides more transparent tone. Using this mode gives a warmer low-end response and lower output. It’s fuzzier with half the output and is the most compressed.   

Each Blumes™ pedal is forged in the deepest, lowest caverns of Akron, Ohio, USA.
