The OKKO FX Twinsonic V2, sold on the maker's site as the TwinSonic MKII, is a dual overdrive pedal that runs internally at 18 volts and carries two differently voiced, stackable channels1. Each channel has its own set of four knobs and a toggle that shapes the bass response, and the two sides can be played on their own or stacked into one bigger drive1.
Two stackable overdrive channels
The pedal's two channels are not identical drives with different paint. The blue channel (left) is the original TwinSonic circuit, which Delicious Audio's Paolo De Gregorio describes as "a dynamic, open-sounding and amp-like overdrive that cleans well with the guitar's volume"1. The same source calls the original TwinSonic "a discrete OD with a bold, open, grainy sound like a cranked vintage amp"1.
The red channel (right) is a transparent low to mid-gain drive that was designed to integrate with the blue side thanks to its smooth gain structure1. In practice that means the pedal can be set up as two independent drives for different songs or guitars, or run stacked, with the red side pushing the blue.
"What we got here is two OD circuits which can be used independently or stacked together."
The controls
Each channel carries four knobs and a toggle1.
| Control | What it does |
|---|---|
| Gain | Sets the drive amount on each channel1 |
| Level | Sets the output of each channel1 |
| Voice | Changes the overall EQ character of each channel, from a wide and full sound on the left to a tighter, punchier sound with pronounced mids on the right1 |
| Mode toggle | Changes the amount of bass frequencies for each side, delivering two different bass EQs1 |
The Gain and Level knobs work as they do on any overdrive1. The Voice knob and the Mode toggle are where the two channels get their separate characters: because each side has its own Voice and its own bass toggle, the blue and red channels can be voiced differently rather than matched.
Power
The TwinSonic V2 runs on 18 volts internally, which Delicious Audio notes is for higher headroom, but it generates that voltage with an internal charge pump circuit, so no special 18V power supply is needed1.
Delicious Audio listed the Twinsonic V2 as an upcoming pedal when it covered it in November 20221.
Where it sits
As a dual overdrive with two stackable channels, the Twinsonic V2 belongs alongside other two-channel drives from OKKO FX, such as the OKKO FX DIABLO DUAL. For a wider look at the category, see the site's page on Overdrive Pedals1.
Questions
Can the two channels of the OKKO FX Twinsonic V2 be used together?
Yes. The Twinsonic V2 holds two overdrive circuits that can be used independently or stacked together. The red channel was designed to integrate with the blue one, so the pedal can work as two separate drives or as a single stacked gain stage with more push.
Does the Twinsonic V2 need an 18V power supply?
No. The pedal runs internally at 18 volts for higher headroom, but it does this with an internal charge pump circuit, so no special 18V power supply is needed. A standard supply works.
What does the Mode toggle do on the Twinsonic V2?
The Mode toggle changes the amount of bass frequencies for each side of the pedal. Each channel has its own toggle, so the two sides can be set with two different bass EQs.
What is the difference between the blue and red channels?
The blue channel is the original TwinSonic circuit, described as a dynamic, open-sounding and amp-like overdrive that cleans up well with the guitar's volume. The red channel is a transparent low to mid-gain drive designed to integrate with the blue side thanks to its smooth gain structure.
