Electro-Harmonix Hot Wax Dual Overdrive Guitar Pedal

SKU CH-3M7G-H0Q61

Dual overdrive pedal combining Hot Tubes and Crayon circuits with independent controls, stackable operation, master EQ, blend knob and 9.6 V 200 mA supply included

  • Two independent overdrive circuits in one pedal
  • Crayon full-range overdrive and Hot Tubes classic CMOS drive
  • Stackable design with Crayon driving Hot Tubes
  • Master two-band EQ plus blend control for tone shaping
  • Includes 9.6 V 200 mA power supply

Dual Overdrive Pedal

The Electro-Harmonix Hot Wax combines two classic overdrive circuits in one enclosure. It merges the Crayon full-range overdrive with the Hot Tubes CMOS reissue for guitar or bass. Players can run each side independently or stack them with the Crayon driving the Hot Tubes. A Master 2-Band EQ and Blend control shape the combined output.

Pedalboard Power Check

Verify your power supply delivers 9.6 V DC at a minimum of 200 mA with a centre-negative barrel connector. The included EHX adapter meets this requirement, but daisy-chain cables must supply adequate current for both circuits. Ensure you have space for a standard-sized pedal and confirm your signal chain order works with pop-free footswitching.

Tone Stacking Players

This unit suits guitarists and bassists who want two distinct overdrive voices plus a stacked option on a single board. It is less ideal for players needing digital modelling, preset recall or MIDI control. Buyers who want more storage for patches or builders who need a second card for stereo rigs should consider other formats.

Questions about this item

What comes in the box and do I need to buy a power supply separately?

The pedal ships with a standard Electro-Harmonix 9.6DC 200mA power supply included, so no separate purchase is required for power.

How do I choose between using the Crayon and Hot Tubes sides independently or stacking them?

Engage each footswitch separately for independent overdrive tones, or activate both to stack the Crayon into the Hot Tubes for thicker saturation.

What does the Master 2-Band EQ actually control on my pedalboard?

The Master 2-Band EQ shapes the overall output of both overdrive circuits together, giving you global bass and treble adjustment after the drive stages.
