The EBS OctaBass Blue Label. Analog octave perfection—now faster, tighter, and more versatile than ever.

The OctaBass was EBS’s first-ever pedal, known for its fast, fat, and natural octave tracking. The Blue Label version builds on that legacy with extended tracking range, tighter tone control, and a compact, modern design.

Key Upgrades:

New Range Switch – Adjust tracking focus higher or lower on the fretboard to better match your playing style.

Expanded Tone Control – Shape your octave from clean and punchy to deep and subby for more of a synth-style bass tone.

Pedalboard-Ready – 12% smaller footprint, 9–18V DC operation, and recessed jacks.

Playing Tip:
For improved tracking, play clean, single notes close to the neck with your fingers or use muted picking. Use a softer touch, if needed. Avoid chords or loose string noise for optimal response. If using a Jazz bass, roll off the bridge pickup to avoid overtones that may trigger the octave response. If using several pedals, make sure the OctaBass get as clean input as possible, and place and drive pedals or filters after the OctaBass.
