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.

Wah & Filter Pedals

Wah effects sweep a resonant band-pass or related filter through the frequency spectrum, creating the vowel-like movement associated with the treadle. Envelope filters move automatically in response to picking level, while fixed and sequenced filters use other control sources. Sweep range, resonance, direction, sensitivity and input loading determine whether the response is vocal, percussive, smooth or sharply synthetic.

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.

Presets

Stores complete groups of parameter values for later recall. The number of locations, switching time, spillover behaviour and whether presets include routing, expression and MIDI assignments determine how completely one sound can change into another.

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.
