The Parallel Dimension from OPFXS is an analog chorus/vibrato pedal built on bucket-brigade (BBD) chips, the same kind of circuit at the heart of classic analog modulation pedals. Where most analog modulation designs work to hide the artifacts of those chips, the Parallel Dimension does the opposite: it gives the player a knob, called Aliasing, that lets the bucket-brigade grit and clock noise back into the signal1.
The pedal was announced on 7 April 2026, when Delicious Audio's Paolo De Gregorio reported the launch1.
Chorus and vibrato
A Chorus/Vibrato toggle switches between the two sides of the pedal. In chorus mode it produces spacious detuning; in vibrato mode it gives pure pitch wobble1. The modulation LFO runs from 0.1 Hz to 11 Hz, a range the maker's launch coverage describes as spanning deep warble to gentle shimmer1. For more on the two effect types, see Chorus Pedals and Vibrato Pedals.
The Aliasing control
The Aliasing knob is the pedal's distinguishing feature. It brings the grit of the BBD chips and their clock noise back into the signal instead of filtering it out1. Delicious Audio describes the two ends of the control this way:
"Low settings behave like tube breakup, soft, organic, a little hair on the glass. Turn it up and the BBD starts revealing"1
At the top of its range the control produces harmonic grit, lo-fi texture and what the launch report calls a digital-meets-analog crunch, like old malfunctioning delays about to die1. The character sits closer to the grit players associate with overdrive pedals and distortion pedals at the low end, and with lo-fi textures at the high end.
Aliasing also works independently of the modulation. With Speed at zero and Depth at zero and Aliasing cranked, the pedal produces just harmonic texture, with no movement, functioning like a lo-fi saturator inside a chorus pedal1.
Power and bypass
The Parallel Dimension is true bypass and draws 20 mA1. That is a light draw, so it should not strain a typical pedalboard power supply.

Questions
Is the OPFXS Parallel Dimension analog or digital?
It is an analog pedal built on bucket-brigade (BBD) chips, the same kind of circuit used in classic analog modulation pedals. Delicious Audio describes it as a pedal that does not try to hide the character of those chips, and its Aliasing control deliberately lets the bucket-brigade grit and clock noise back into the signal.
Is the OPFXS Parallel Dimension true bypass?
Yes. Delicious Audio's report on the pedal lists it as true bypass, with a 20 mA current draw.
How much current does the OPFXS Parallel Dimension draw?
The pedal draws 20 mA, according to Delicious Audio's launch report. That is a modest draw by pedal standards, so it should sit comfortably on a shared power supply alongside other compact pedals.
Can the OPFXS Parallel Dimension do vibrato as well as chorus?
Yes. A Chorus/Vibrato toggle switches between the two: chorus mode gives spacious detuning, while vibrato mode gives pure pitch wobble with no blended dry signal character.
What does the Aliasing control do on the Parallel Dimension?
Aliasing lets the grit of the bucket-brigade chips and their clock noise back into the signal. At low settings Delicious Audio compares it to tube breakup, soft and organic. Turned up, it produces harmonic grit and lo-fi texture, like an old malfunctioning delay about to die. It also works with the modulation turned down, acting like a lo-fi saturator.
