Electro-Harmonix Dirt Road Special - 40 Watt Combo Amp

Electro-Harmonix Dirt Road Special - 40 Watt Combo Amp

The EHX DIRT ROAD SPECIAL is a reissue of our vintage 1970s amp with modern enhancements to both the electronics and mechanical design. We’ve also added four reverbs from our Holy Grail Max reverb pedal: spring, plate, hall, and reverse.

The DIRT ROAD SPECIAL offers the advantages of a solid state design – lighter weight, smaller size and improved portability – but its classic circuitry delivers a natural crunch and overdrive with beautiful grit and grind. And, with 40 watts and one 12 inch speaker, you have the perfect amp for any occasion.

FRONT PANEL Controls:

INPUT Jack – This ¼” jack is the audio input for the amplifier. The input impedance is 1.5MΩ.

VOLUME Knob – Controls the overall loudness and gain of the amplifier. We recommend turning down VOLUME prior to applying power. Turn up the VOLUME knob after the amp has been powered up for at least five seconds.

TONE Knob – Alters the amplifier’s frequency response. Turning this control counter-clockwise increases bass and turning it clockwise increases treble.

BITE Knob – Alters the amplifier’s gain level and frequency response. Turning this control clockwise increases the gain and treble content. This control is also very interactive with the VOLUME control; changing one affects the other.

REVERB Knob – Controls the volume of the reverb. When the reverb footswitch is not connected to the back panel via a ¼” mono instrument cable, the reverb is always on.

TIME Knob – Adjusts the decay time, or reverb length/size, for the SPRING,

HALL and PLATE reverbs. In REVERSE mode, the TIME knob sets the length of time between striking a note and the reverb fade-in. While in PLATE mode, when TIME is set to its maximum position, the reverb decay is over 30 seconds, creating a lush reverb wash with each new note.

Reverb Switch Knob – Chooses the reverb mode. From left to right, the

modes are SPRING, HALL, PLATE, and REVERSE.
