Origin Effects DCX Boost

The Origin Effects DCX Boost is a boost and preamp pedal for electric guitar that recreates the circuit of the Universal Audio 610 studio preamp in stompbox form. Origin Effects launched it in April 2023 alongside a bass sibling, the DCX Bass, and both are designed and built in England¹². Rather than copying one classic pedal, the DCX takes its character from a piece of studio hardware: the UA 610 preamp, used in its original form to record a long list of American musicians³¹⁴.

In practice the pedal can serve as a drive section, an EQ, or a tone-sweetening boost in front of an amp⁵. Guitar World's reviewer Trevor Curwen called it "a really versatile boost and drive with tightly focused EQ options" and said that if restricted to just one pedal in front of an amp, "this is the one we'd choose"⁶.

A UA 610 preamp in pedal form

The DCX Boost is inspired by the UA 610 studio preamp, a piece of recording equipment Origin Effects describes as a classic¹. The company says recreating the 610 circuit in pedal form means "you're not constrained to a certain signal chain order," so the pedal can sit anywhere on a board rather than needing a fixed position⁹.

The UA 610 lineage shows up in how the pedal handles gain. Origin Effects positions it as a touch-responsive low-gain drive that reacts to playing dynamics and volume knob changes, moving between clean and overdriven tones in a very natural way⁹. For players who want that kind of response, the company suggests running the DCX first in the chain⁹.

EQ mode and OD mode

A Mode switch on the pedal selects between two voicings, EQ and OD, which together cover a wide gain range⁶.

EQ mode is the lower-gain setting of the two and the go-to mode for clean boost, though at higher Drive settings it is capable of drive for adding grit to clean sounds and covering edge-of-breakup and beyond⁶. It is designed to be responsive to playing dynamics and also to the guitar's controls, sitting somewhere between clean and overdriven with a seamless transition and a treble roll-off when pushed hard¹⁰. Origin Effects recommends EQ mode for cleaner or mildly overdriven tones and tone shaping⁹.

OD mode is the higher-gain option. It rolls off top-end and has three distinct voicings labeled Dark, Flat and Medium, selected by the Voice switch¹⁰. Guitar World notes there is no Adaptive Circuitry in OD mode, but there is a tighter low-end and a natural treble to suit drive sounds, plus extra attenuation via the Voice switch⁶.

Adaptive Circuitry

In EQ mode, Origin has incorporated its Adaptive Circuitry, which keeps clean sounds bright and sparkly, reining back the treble with increasing drive⁶. The manual describes the feature as "adjusting the pedal's voicing in response to playing dynamics and volume knob changes"³. The practical effect is that the pedal cleans up when you back off your guitar's volume and darkens itself as you push the Drive knob, without you having to re-dial the EQ.

The controls

The DCX Boost keeps its control set compact: four knobs, two switches and one footswitch⁶.

Origin Effects suggests a starting point of Level at maximum and Drive at minimum, which gives unity gain; from there, increasing the Drive control takes advantage of the pedal's clean boost range⁹. The L.F. and H.F. controls can be used against each other, for example an L.F. cut paired with a slight H.F. boost⁹.

Power: 9V, 90mA

The DCX Boost runs on a 9V DC adaptor that is not supplied, drawing 90mA⁶. Both DCX pedals take 9V DC from a pedalboard power supply⁵, and the DCX line dispenses with the usual 9V battery option, so the pedal cannot run without external power⁴.

The DCX Bass

The DCX Boost has a bass sibling, the DCX Bass, which reimagines the same UA 610 preamp as a tone-shaper and drive pedal for bass guitar⁴. Its gain range runs from clean boosts and direct-to-console sounds, through edge-of-breakup and low gain drives, all the way to almost fuzz-like tones⁴. Like the guitar version, it uses a high-quality buffered bypass and 9V DC 2.1 mm center-negative power⁴. Players comparing the two can read more in the bass pedals category.

What reviewers said

Guitar World's review concluded that the DCX is "a really versatile boost and drive with tightly focused EQ options," and that if the reviewer were restricted to just one pedal in front of an amp, this would be the one chosen overall⁶. The pedal also appeared on That Pedal Show, featured in the episode "Choosing A Digital Delay For Guitar" in November 2023².
