EarthQuaker Devices Tone Job OPERATION MANUAL
Tone Job
™
Is your tone pulling its weight? Put it to work with a Tone
Job™! This compact Boost & EQ Device is based around the
tone-shaping options available in old audiophile-grade stereo
preamps, making it a great addition to your pedalboard no
matter what instrument you play.
So what does that mean, exactly? It means that you’ll hear full
frequency response from your Tone Job everywhere you plug
it in – guitar, bass, drum machine, synthesizers, steel drums,
harpsichord, kazoo, car stereo*, or wherever!
The Tone Job has active EQ controls for “Bass,” “Mid,” and
“Treble,” with up to 20 dB of cut or boost, which is handy for
pairing up with other pedals in your chain to breathe new life
into old dirt. Unlike boring old graphic EQs, the Tone Job’s EQ
controls are interactive, so you can experiment with different
settings to alter the response and overall feel of the Device,
getting your tone out of the lunchroom and back on the clock.
Place the Tone Job at the beginning of your chain to alter the
overall character of your guitar, or use it at the end to boost
output at the end of a long cable run and ne-tune your tone.
The “Level” control on the Tone Job can boost your signal up
to 5x the original input level, so you’ll always be heard, and
makes for a fantastic solo and/or clean boost!
*We haven’t actually tried the Tone Job on our car stereos,
but it probably sounds pretty good if you can gure out how
to patch it in!
The Tone Job is all analog, true-bypass and built one-at-atime by a bunch of standing waves and a few bass traps in
acoustically challenged Akron, Ohio, USA.
Controls
Level: Post EQ volume control. Can boost the signal up to 5x
the input. Unity is around 10 O’Clock.
Treble: The center position is at and marked with a center
detent in the potentiometer. All settings above this point boost
the treble and all settings below cut treble.
Bass: The center position is at and marked with a center
detent in the potentiometer. All settings above this point boost
the bass and all settings below cut treble.
Middle: The center position is at and marked with a center
detent in the potentiometer. All settings above this point boost
the middle and all settings below cut treble.
Treble affects frequencies from around 2k Hz up, bass affects
frequencies from around 500 Hz down. The middle is an
adjustable resonant lter acting as a midrange control with it’s
center frequency around 1k Hz. Treble and bass response are
dependent on middle control settings.
Power
The Tone Job should be powered by a standard 9-18 volt DC
power supply intended for musical instruments with a negative
center 2.1mm barrel. We strongly recommend a high quality
power supply with isolated outputs and good ltering to avoid
unwanted noise.
Current Draw: 10mA
Input impedance: 1M
Output impedance: 1K
Switching
This device is true bypass and uses electronic relay based
switching. Audio will not pass without power.
