Dual Overdrive

Congratulations on your purchase of the Electro-Harmonix Hot Wax. The Hot Wax is a unique dual overdrive pedal that combines the distortion sections used by two EHX classics: the Crayon and the Hot Tubes. Each section can be engaged independently, for two very different overdrive flavors, or together to create a massive overdriven sound. The Hot Wax is a flexible and great-sounding distortion unit useful for guitar, bass, keyboards, and many other musical instruments.

The Hot Wax includes a two-knob EQ (BASS and TREBLE) for extensive tonal control, and a BLEND control to mix between your dry and distorted sound. These three controls are active with either or both distortion sections engaged, and bypassed when both overdrive section are turned off. The Hot Wax features buffered bypass and is powered by a standard 9V power jack.

WARNING: Your Hot Wax comes equipped with an Electro-Harmonix 9.6DC-200BI power supply (same as used by Boss® & Ibanez®: 9.6 Volts DC 200mA). The Hot Wax requires 75mA at 9VDC with a center negative plug. Use of the wrong adapter or a plug with the wrong polarity may damage your Hot Wax and void the warranty.

Plug the included power adapter into the 9V jack. The pedal must be powered to pass a signal through, regardless of whether or not distortion is engaged. Step on the CRAYON footswitch to engage the Crayon section. The green LED lights to indicate that the Crayon is on. Click the HOT TUBES footswitch to turn on the Hot Tubes section, as indicated by the red LED.

The BASS & TREBLE EQ and BLEND controls are active when either one or both sections are in use. When only one section is active, adjust that section’s VOL (volume) knob to set the master volume. When both sections are active:

• The Crayon comes first in the signal path.
• The Crayon’s VOL knob sets the level driving the Hot Tubes section.
• The EQ affects the signal after the Hot Tubes’ distortion section.
• The BLEND knob combines the clean signal with the post-EQ signal.
• The Hot Tubes’ VOL knob functions as the master volume.

Footswitches and LEDs
The right LED (green) illuminates when the Crayon section is engaged via the footswitch. The left (red) LED lights when using the Hot Tubes section.

VOL Knob (Crayon)
If only the Crayon is active, the VOL knob sets master output level. If both sections are active, the VOL knob sets the level between the Crayon’s drive section and the Hot Tubes’ drive section.

VOL Knob (Hot Tubes)
Use the Hot Tubes VOL knob to set the master output level.


Turn the appropriate DRIVE knob to set the distortion intensity.

BASS and TREBLE Equalization Knobs
Adjust the BASS knob to boost or cut low frequencies. Adjust the TREBLE knob to boost or cut high frequencies. The frequency response for either knob is flat (no boost or cut) when the knob is set halfway up.


The BLEND knob mixes the dry and distorted signal. With BLEND set to minimum (fully counterclockwise), you will only hear the dry signal. When BLEND is turned fully clockwise, you will only hear the distorted signal. All other settings will yield varying mixtures of dry and distorted sounds.

Turning BLEND down to add dry signal can add more punch and clarity, along with more emphasis on pick attack. This functionality may be of particular importance to bassists, as full-on distortion can reduce punch and muddy up low end frequencies.


Plug your instrument or the output of another effects pedal into the ¼” INPUT jack. The input impedance is 2.2M.

Use the ¼” OUTPUT jack to send the signal to an amp or another effects pedal. The signal will be dry or effected based on the bypass status. The output impedance is 220.

Plug the output of the included EHX 9.6DC-200 adapter into the 9V power jack of the Hot Wax. The Hot Wax draws 75mA at 9VDC with a center negative plug. The Hot Wax accepts Boss® and Ibanez® style AC Adapters capable of delivering at least 200mA.

The Hot Wax does not accept batteries, and only works with an external 9V power supply. Do not open the unit as there are no user serviceable parts.

• The Hot Wax utilizes a high quality buffered bypass.
• Input Impedance: 2.2M 
• Nominal Output Impedance: 220
• Current Draw: 75mA
