The T-Rex Twister II is a chorus and flanger pedal from T-Rex1. T-Rex bills it as "a chorus and flanger pedal for guitarists who demand nothing less than the best"2. According to the company, adjusting the Depth, Tone and Rate controls lets the pedal deliver "both old-fashioned vintage sound as well as a more modern chorus sound"1.
What it does
The Twister II covers two modulation effects in one box. A dedicated chorus/flanger control selects between them, and T-Rex says that by adjusting Depth, Tone and Rate you can take the chorus from "warm vintage-sounding chorus" to a "modern chorus" sound2. The full control set is:
| Control | Function |
|---|---|
| On/off | Bypasses or engages the effect |
| Input gain | Sets the signal level going into the effect |
| Level | Sets the overall output level |
| Depth | Sets modulation intensity |
| Regen | Flanger feedback control |
| Speed | Sets modulation rate |
| Tone | Shapes the tonal character |
| Chorus/flanger | Selects the effect mode |
The pedal also offers a stereo output, adjustable maximum input signal (V p-p), input impedance higher than 1M Ohm at 1KHz, and output impedance lower than 1K Ohm at 1KHz2.
Power and battery
The Twister II runs on 9V DC, with T-Rex naming its own FuelTank supply, and draws 85 mA2. It does accept a 9V 6F22 battery, but the maker lists battery life at only 30 to 60 minutes2.
At 85 mA, the Twister II draws more current than many daisy-chain supplies deliver comfortably, and battery life of 30 to 60 minutes is short. A dedicated 9V DC supply is the practical way to run it.
Twister II versus the original Twister
T-Rex describes the update in the maker's own words:
"We gave the Twister a face-lift based on your feed-back and it is now completely updated with new hardware and software."
The light/heavy switch on the original was removed, and the pedal now covers a wider tonal range, with the tone control and chorus/flanger switch handling that job instead2.
Size and weight
The pedal measures 100 x 55 x 120 mm / 3,9 x 2,2 x 4,7 inch (W x H x D) including knobs, and weighs 0,350 kg / 12,3 oz excluding packaging2.
Related pedals
The Twister II sits in T-Rex's line of chorus-family pedals, with controls covering both chorus and flanger modes: on/off, input gain, level, depth, regen, speed, tone, and a chorus/flanger switch1. For a wider look at the effect type, see Chorus Pedals and Flanger Pedals.

Questions
Does the T-Rex Twister II take a battery?
Yes. T-Rex specifies a 9V battery of the 6F22 type, the standard rectangular 9V battery used in most pedals. The maker also lists battery life at 30 to 60 minutes, which is short by pedal standards, so most players will want to run the Twister II from a 9V DC power supply rather than rely on a battery.
Is the T-Rex Twister II stereo?
Yes. T-Rex lists a stereo output as a feature of the Twister II. The pedal's external connectors are an input jack, an output jack and a 9V DC jack, so the stereo output comes from that single output jack rather than a pair of separate outputs.
What is the difference between the Twister and the Twister II?
T-Rex describes the Twister II as a face-lift of the original Twister, completely updated with new hardware and software based on player feedback. The light/heavy switch on the original was removed, and the pedal now covers a wider tonal range, with the tone control and chorus/flanger switch taking over that job.
Can the Twister II do both chorus and flanger?
Yes. T-Rex bills it as chorus and flanger in one pedal, selected with a dedicated chorus/flanger control. In chorus mode the maker says the Depth, Tone and Rate controls reach from a warm vintage-sounding chorus to a modern chorus sound, and the same control set serves the flanger mode.
How long does a battery last in the Twister II?
T-Rex lists battery life at 30 to 60 minutes. That is short, and it follows from the pedal's current draw of 85 mA at 9V DC, which is well beyond what a 6F22 battery comfortably delivers. Plan on using a 9V DC power supply such as the T-Rex FuelTank for anything beyond a quick test.
