TC Electronic Nether Octaver Sub Octave Guitar Effects Pedal

Guitarists often struggle to fatten up their tone or create earth-shaking low-end without adding digital artifacts or losing note definition. The TC Electronic Nether Octaver solves this with a fully analog circuit that generates two sub-octave voices—one octave down and two octaves down—while preserving your dry signal. Blend the three signals with dedicated Dry, Octave, and Sub controls to go from subtle thickening to monstrous synth-like lows. Housed in a rugged die-cast metal enclosure with true bypass, this compact pedal is built for the road and integrates seamlessly into any pedalboard.

Who is it for

The Nether Octaver is ideal for electric guitarists seeking to expand their sonic palette—from blues and rock players wanting a thicker lead tone to experimental musicians crafting bass-like textures or octave fuzz sounds. It’s also a powerful tool for bassists looking to add sub-harmonic depth, though it is primarily designed for guitar. Whether you play live or record in the studio, this pedal delivers reliable analog octave effects without menu diving.

Main features

• All-analog octaver circuit for warm, organic sub-octave tones
• Three independent controls: Dry, Octave (one octave down), and Sub (two octaves down)
• True bypass preserves your original signal when the effect is off
• Heavy-duty metal footswitch with LED indicator for on/off status
• Compact mini pedal form factor fits easily on crowded pedalboards
• Die-cast metal enclosure for durability on stage and in transit
• Standard 9V DC center-negative power input (power supply not included)
• High input impedance (470 kOhm) maintains guitar signal integrity
• Low output impedance (1 kOhm) ensures compatibility with long cable runs

Tips

For a classic octave fuzz tone, set Dry to noon, Octave to 3 o’clock, and Sub to 9 o’clock, then run the Nether Octaver into a distortion pedal. To create a faux bass line, turn Dry fully counterclockwise and blend Octave and Sub to taste. Use a regulated 9V power supply to avoid unwanted noise, and place the pedal early in your chain for the best tracking.
