The TWA Wahsabi is a treadle-operated wah pedal from TWA, a maker with a long line of filter pedals including the Triskelion, the Dynamorph and the Little Dipper. Where a traditional wah-wah only sweeps the center frequency, TWA says the Wahsabi offers control of not only the center frequency, but the degree to which that frequency is emphasized. The pedal takes the band-pass filter of the Triskelion and serves it up under a treadle, aimed at the throaty, mid-heavy, focused guitar tones the maker associates with 1970s classic rock recordings by bands such as Boston, UFO, Aerosmith and Kiss.1
What it does to your sound
The Wahsabi is built around the Triskelion's band-pass filter, which TWA describes as brash, beefy and bombastic. In a band-pass filter, only the frequencies around the selected center point pass through, which is what gives a wah its vocal, peaked character. The Wahsabi's addition is a second dimension of control: alongside where the peak sits, you can set how strongly that peak is emphasized. TWA positions the pedal as perfect for creating the mid-heavy, focused tones of 70s classic rock.1
Modes and the treadle
TWA lists four ways to use the pedal:
- Standard wah-wah: the treadle sweeps the frequency as on a conventional wah
- Solo booster: the filter parked as a boost
- Wah/booster: both at once
- Resonant feedback generator: pushing the signal into controlled feedback1
The treadle selects the frequency. A jack for an external momentary switch offers the option to activate the Wahsabi on the fly without altering the frequency selected by the treadle, so you can leave the treadle where you want it and bring the effect in with a switch.1
As of 26 October 2026, the Wahsabi was listed as sold out and available as pre-order, with a scheduled release of June 15th, 2026.1
Where it sits in TWA's filter range
The Wahsabi joins a filter-heavy lineup from TWA. The Triskelion is the circuit the Wahsabi is based on, a midrange gain and frequency-shaping pedal; the DM-02 Dynamorph responds to playing dynamics; and the Little Dipper Mk II is an envelope-controlled formant filter. Players comparing treadle wahs may also want to look at TWA's Wah Rocker line, and the broader field of filter pedals and wah-wah pedals.1

Questions
What is the TWA Wahsabi based on?
TWA says the Wahsabi takes the band-pass filter circuit of the Triskelion, the company's midrange gain and frequency-shaping pedal, and serves it up in a treadle-operated wah format. The treadle selects the center frequency, while the Wahsabi adds control over how much that frequency is emphasized, something a traditional wah does not offer.
How is the Wahsabi different from a traditional wah?
According to TWA, a traditional wah-wah only sweeps the center frequency. The Wahsabi lets you control not only the center frequency but also the degree to which that frequency is emphasized, so you can shape how pronounced the peak is as well as where it sits.
Can I turn the Wahsabi on without using the treadle?
Yes. The Wahsabi has a jack for an external momentary switch, which lets you activate the effect on the fly without altering the frequency selected by the treadle. That means the treadle can stay parked at your chosen frequency while a separate switch brings the effect in and out.
What modes does the TWA Wahsabi have?
TWA lists four ways to use the Wahsabi: as a standard wah-wah, as a solo booster, as a combination wah and booster, or as a resonant feedback generator. The mode you choose changes whether the pedal sweeps, boosts, does both, or pushes the signal into feedback.
When was the TWA Wahsabi released?
The Wahsabi was offered as a pre-order with a scheduled release date of June 15th, 2026. As of late October 2026, TWA's product page listed the pedal as sold out and available as a pre-order.
