The T-Rex Twister II is a chorus and flanger pedal from T-Rex Engineering, described by the maker as built "for guitarists who demand nothing less than the best." It puts both effects in one enclosure, with a chorus/flanger switch to move between them, and a stereo output for running two paths to an amp or rig1.
T-Rex says that by adjusting Depth, Tone and Rate, the Twister II delivers "both old-fashioned vintage sound as well as a more modern chorus sound." The maker describes its modes as "Warm vintage-sounding chorus or modern chorus"1.
Controls
The Twister II carries eight controls, which is more than most chorus or flanger pedals offer and gives direct access to the shape of the effect rather than hiding it behind menus or presets1.
| Control | What it does |
|---|---|
| On/off | Engages or bypasses the effect |
| Input gain | Sets how hard the circuit is driven |
| Level | Sets the output volume |
| Depth | Sets the intensity of the modulation |
| Regen | Sets the amount of feedback in the flanging circuit |
| Speed | Sets the rate of the modulation |
| Tone | Shapes the tonal character |
| Chorus/flanger | Selects between the two effects |
Power and connections
The pedal runs on 9V DC, with T-Rex naming its own FuelTank power supply, and draws 85 mA at 9V DC. External connectors are an input jack, an output jack and a 9V DC jack1.
The Twister II also takes a 9V 6F22 battery, but T-Rex gives a battery life of only 30 to 60 minutes1. At 85 mA of current draw, this is a pedal that suits a dedicated power supply, and a battery is at best a short-term fallback.
From the Twister to the Twister II
T-Rex introduced the Twister II as the next generation of the original Twister, calling it "a completely updated with new hardware and software" after revising the design in response to player feedback. Two things changed in the update: the light/heavy switch was removed, and the pedal now covers a wider tonal range1.
The removal of the light/heavy switch means the Twister II reaches its range of sounds through the Depth, Tone and Rate controls instead, and the wider tonal range is the maker's stated reason a player can get both vintage-flavored and modern chorus sounds from the same pedal1.

Questions
Does the T-Rex Twister II have stereo output?
Yes. T-Rex Engineering lists stereo output among the Twister II's features, alongside its input jack, output jack and 9V DC jack. The pedal's impedance figures, higher than 1M Ohm input and lower than 1K Ohm output at 1KHz, are given at 1KHz on the maker's product page.
How long does a battery last in the T-Rex Twister II?
T-Rex Engineering gives a battery life of 30 to 60 minutes with a 9V 6F22 battery. That is short compared with a typical pedal, a result of the pedal's 85 mA current draw at 9V DC, so most players run it from a power supply rather than a battery.
What changed between the Twister and the Twister II?
T-Rex describes the Twister II as a completely updated version of the original Twister, with new hardware and software, revised in response to player feedback. The light/heavy switch was removed, and the pedal now covers a wider tonal range.
Can the T-Rex Twister II do both vintage and modern chorus?
Yes. T-Rex says that by adjusting Depth, Tone and Rate the Twister II delivers both old-fashioned vintage sound and a more modern chorus sound, and the maker describes its modes as warm vintage-sounding chorus or modern chorus.
What power supply does the T-Rex Twister II use?
The Twister II runs on 9V DC, with T-Rex naming its own FuelTank supply. It draws 85 mA at 9V DC and also accepts a 9V 6F22 battery, though the maker's stated battery life of 30 to 60 minutes makes a power supply the practical choice.
