The TWA Blabbermouth is a filter effects pedal from Totally Wycked Audio, distributed in the United States by Godlyke Distributing. The maker describes it as "the pedal that just won't shut up": a single unit that can emulate talkboxes, filters, phasers or flangers, or produce what the maker calls "incredibly vocal-sounding wah-wah" effects1.
What it does
The Blabbermouth works with two custom-tuned filters that continuously sweep against each other. According to the maker, this creates "throaty vowel sounds" and "amazingly realistic diphthongs" that simulate the complexities of human speech, which is what sets it apart from a standard filter pedal or wah1.
The maker describes the pedal's lineage plainly: "The bastard child of an EH Talking Pedal, a Colorsound Vocalizer, and our own engineer's twisted machinations"1. Players familiar with those vintage units will recognize the family resemblance in intent, if not in circuitry.
Controls and connections
The pedal keeps its control set small:
- A side-mounted pot to adjust the harmonic content of the effect1
- A jack for connecting an external momentary switch, which lets you activate the effect on the fly without altering the frequencies selected by the treadle1
The external switch jack is aimed at players who want to punch the vocal effect in and out mid-phrase while leaving the treadle position untouched1.
Price and availability
Godlyke lists the Blabbermouth at a regular price of £230.00 GBP1. As of 26 October 2026, the pedal is shown as sold out at Godlyke1.
The Blabbermouth is listed as sold out at Godlyke, its US distributor. Players looking at TWA's current filter range may also come across the Little Dipper 2.0, an envelope-controlled vocal formant filter, or the LF-01 Ladditude, an envelope-controlled resonant filter.
