Origin Effects RD COMPACT HOT ROD

Connecting the RD COMPACT HOT ROD

INSTR: 

Connect to your guitar, bass or other instrument. 

AMP:

 Connect to your amp, power amp, mixer or recording interface. If you’re playing through 

something other than a guitar speaker (e.g. PA speakers, studio monitors, headphones or direct 

recording), we strongly recommend using a speaker simulator after the RD Compact Hot Rod.

9VDC: 

Connect a 9VDC 2.1mm centre-negative mains power adaptor (minimum 100mA). 

Main controls

OUTPUT: 

The output control sets the pedal’s overall output level. As it isn’t part of the RD Compact Hot 

Rod’s emulated amp circuitry, the 

OUTPUT

 control won’t alter the pedal’s overdrive character. It simply 

lets you make it louder or quieter. 

GAIN: 

The 

GAIN

 control functions exactly like the volume knob on a non-master-volume valve amp. 

Turn it clockwise for more gain, sustain, drive and distortion. Turn counterclockwise to clean things up. 

BLEND: 

This control lets you adjust the mix between the dry input signal (DRY) and the overdriven 

signal created by the RD Compact Hot Rod. As mixing clean and very heavily overdriven signals tends to 
produce undesirable results, we’ve designed the 

BLEND

 knob to gently back off the gain as you mix in 

more dry signal. 

Set the control fully clockwise (100% O.D.) then turn it counterclockwise to progressively mix your 
original clean signal back in, delivering a rounder, fuller and more natural tone. 

HIGHS: 

The 

HIGHS

 knob progressively increases mids and highs as you turn it clockwise, delivering a 

brighter, more incisive tone while keeping the low end tight and controlled so that high-gain settings don’t 

turn to mush. 

The 

HIGHS

 knob provides a continuous range of useful preamp voicings, ranging from a Marshall

®

-style 

amp with its tone controls centred (

HIGHS

 set fully counterclockwise), to a late ‘70s Master Volume 

Marshall

®

 (

HIGHS

 at 12 o’clock) to a cranked modded Fender

®

 amp (fully clockwise).
