CRAYON
Full-Range Overdrive
Congratulations on your purchase of the Crayon, a colorful overdrive in a
compact, pedalboard-friendly enclosure. Unlike many mid-focused overdrive
pedals, the Crayon is a full-range overdrive with rich harmonic content and a full
bodied tone allowing you to dial in the perfect overdrive for any situation. The
GAIN knob ranges from just a touch of dirt to full-on distortion while individual
BASS and TREBLE controls open up the frequency response capabilities of the
Crayon yielding a wide range of versatile overdriven sounds.
- CONTROLS -
GAIN Knob –Controls the amount of input gain. As you turn GAIN clockwise,
the overdrive ranges from just a touch of grit, in the fully counter-clockwise
position, to classic distortion, in the fully clockwise setting.
TREBLE Knob –As you turn TREBLE clockwise, the overdrive’s high end is
accentuated, making your tone brighter. Turn TREBLE counter-clockwise for a
darker sound.
BASS Knob –As you turn BASS clockwise, the low end is boosted. Turn BASS
counter-clockwise to reduce low end.
VOL Knob –Sets the output level of the Crayon. As VOL is turned clockwise, the
output volume increases.
FOOTSWITCH and LED –The Footswitch selects whether the Crayon is
engaged or in true-bypass mode. When the effect is engaged, the LED is lit.
INPUT Jack –This ¼” jack is the audio input for the Crayon. The input
impedance is 315k.
AMP Jack –This ¼” jack is the audio output from the Crayon. The output
impedance is 50.
9V Power Jack –The Crayon can run off of a 9V battery or you can use an
optional 9VDC AC Adapter capable of delivering at least 25mA to the 9V power
jack, such as the Electro-Harmonix 9.6DC-200 power supply. The AC Adapter
must have a center negative plug. The battery may be left in or taken out when
using an AC Adapter. The Crayon has a current draw of 10mA at 9VDC.
