The EarthQuaker Devices Blumes Jr MOSFET Mod Bass Overdrive Pedal is a compact bass overdrive designed to deliver powerful saturation without sacrificing low-end presence. Building on the original Blumes circuit which doubles the gain of the Plumes and extends its bass response this limited-edition pedal introduces a dedicated MOSFET clipping mode for tight focused overdrive. Its three selectable clipping options cover everything from articulate crunch and clean boosting to harmonically rich distortion making it a versatile choice for bassists looking for extra character and aggression. The MOSFET Mod setting produces a commanding overdrive with enhanced low end and a dynamic response inspired by cranked high-gain valve amps. Symmetrical LED clipping offers compressed focused drive while the no-clipping mode provides open OpAmp boosting. Gain Tone and Level controls make it easy to shape your sound with a versatile EQ response that balances substantial bass prominent mids and cutting highs. Mechanical true bypass switching maintains a direct signal path when disengaged while the smaller enclosure makes this pedal a practical addition to crowded pedalboards.

EarthQuaker Devices
Musician Jamie Stillman founded EarthQuaker Devices in 2004 after moving from pedal repair into circuit design. The first full-production release was the Hoof fuzz in 2007. The company develops its pedals in-house in Akron, Ohio, where it hand-builds and hand-tests them and backs them with a lifetime guarantee. Current JustPedals examples show the range’s practical and exploratory sides: Ghost Echo reverb, Data Corrupter harmonizer, Avalanche Run delay and reverb, and Rainbow Machine pitch shifting. EarthQuaker’s own design philosophy pairs usable controls with sounds that can move well beyond conventional effects.

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.
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.
