EarthQuaker Blumes Jr MOSFET Mod Limited Edition Low Signal Shredder

The limited edition EarthQuaker Devices Blumes Jr MOSFET Mod delivers bass-ready overdrive with three selectable voices in a compact enclosure. This modified version of the Blumes adds MOSFET clipping for a substantial low end, harmonically rich saturation, and a dynamic response inspired by a modern high-gain tube amp.

A three-way toggle covers everything from a clean boost to aggressive drive. Mode L uses symmetrical LED clipping for crunchy, articulate overdrive with plenty of output. Mode N removes the clipping diodes for a broad-frequency OpAmp boost, staying clean with the Gain below 11 o’clock. Mode M introduces the MOSFET circuit, delivering smooth saturation with added low-end weight and definition.

Gain, Tone, and Level controls let you adjust the amount of breakup, shape the frequency balance, and set the output to suit your rig. Mechanical true bypass switching keeps the signal path clear when disengaged. Requires a standard 9V DC center-negative power supply.
