The Cog Effects T-16 is an analog octave pedal from the UK maker Cog Effects, designed to generate a note one octave below what you play while your clean signal carries on underneath. Cog Effects has described it as the smallest analog octave pedal in the world, and each unit is built one at a time12. It belongs to the wider family of octave and pitch pedals, and it works for guitar and bass.
What it does and how it is controlled
The T-16 produces an octave-down signal that sits alongside your dry tone, and a Clean blend control sets the wet/dry ratio between the two. The octave-down voice itself is shaped by a variable Filter control: Guitar Interactive Magazine described it as adjusting the octave down signal "from buzzy and synthy through to fat and subby tones"1. That range is the heart of the pedal, since the same octave-down note can read as a synth-style effect or as a deep low foundation depending on where the Filter is set.
The pedal's build is aimed at pedalboards short on space: an all-metal small footprint enclosure with true bypass switching, so the pedal is out of your signal path when off3.
What reviewers said
Delicious Audio's reviewer Brandon Stoner found the T-16 blends well with a rig and pairs effectively with fuzz3:
"Paired with your favorite fuzz, you can definitely get into Jimi Hendrix territory with this pedal, and the controls all..."
That points to a common use: running the T-16 into a fuzz pedal for octave-down fuzz sounds in the Hendrix style, with the Clean blend keeping the dry note intact underneath3.

Questions
Is the Cog Effects T-16 analog or digital?
The T-16 is an entirely analog pedal. Delicious Audio's reviewer Brandon Stoner described its signal path as entirely analog, and Cog Effects has described the T-16 as among the smallest analog octave pedals in the world. That matters for players who want an octave-down effect without the latency or conversion of a digital design.
What does the Filter control on the T-16 do?
The Filter control adjusts the voice of the octave down signal. Guitar Interactive Magazine described its range as running from buzzy and synthy tones through to fat and subby tones, so you can dial the generated octave down from thin and synthetic sounding to deep and full depending on the instrument and the sound you are after.
