The Terrordactyl is a stompbox from Fuzzrocious Pedals that puts two effects in one box: a fuzz that feeds into an envelope filter. No Treble's Kevin Johnson announced it in September 2011 as "a fuzz that feeds into an envelope filter all in one stompbox," available at launch for $1701. It belongs to the same family as fuzz pedals and filter pedals, but combines the two in series so the filter responds to the fuzzed-up signal.
Controls and features
The pedal's three controls include volume, envelope level, and envelope range1. Volume sets the overall output, envelope level shapes the filter's output, and envelope range sets how far the filter sweeps.
Beyond the knobs, the Terrordactyl carries two features worth noting:
- An expression pedal output to adjust the envelope's range on the fly, so a player can sweep the filter response with a foot pedal rather than only with the knob1
- A bright violet LED as the indicator1
Power and bypass
The Terrordactyl is powered by a "Boss"-style 9 volt adapter, the standard center-negative supply used by most compact pedals1. When switched off, it features true bypass1.
Build and availability
Fuzzrocious built the Terrordactyl to order, hand-made and painted in the U.S., in a hand-painted blue sparkle enclosure1. At its September 2011 release it was available for $1701.

Questions
Is the Fuzzrocious Terrordactyl true bypass?
Yes. No Treble's announcement of the pedal states that the Terrordactyl features true bypass, so the signal passes through unaffected when the pedal is switched off.
What power supply does the Terrordactyl need?
The Terrordactyl is powered by a Boss-style 9 volt adapter, the same center-negative standard used by most compact pedals, so it can share a supply with typical pedalboard power.
Can you use an expression pedal with the Terrordactyl?
Yes. The pedal includes an expression pedal output that adjusts the envelope's range on the fly, letting a player sweep the filter's response during a performance rather than leaving it fixed by the envelope range knob.
Where is the Terrordactyl made?
The Terrordactyl is hand-made and painted in the U.S. Fuzzrocious built the pedals to order, each in a hand-painted blue sparkle enclosure.
Is the Terrordactyl a fuzz or an envelope filter?
It is both. No Treble described it as a fuzz that feeds into an envelope filter all in one stompbox, so the fuzz section drives the filter section in a single enclosure.
