CELEBRITY PEDALS Docta Philter (Octave and Envelope Filter)

Handmade, Analog and True Bypass. Octave / Envelope Filter.

First, our legendary octave circuit with a low pass filter knob and dry signal killswitch. Then an envelope filter based on our favourite elements of the Mutron and the Mini Q-Tron.
Use each effect individually or use them simultaneously for ultimate synth glory.

Key Features

• Octave & Envelope Filter in One – No need for two separate pedals.
• Low-Pass Filter Control – Shape the octave tone from smooth and deep to bright and punchy.
• Dry Signal Kill Switch – For pure octave effects without any clean blend.
• True Bypass – Your tone stays pure when the pedal is off.
• Handmade Analogue Circuitry – Boutique build quality with vintage-inspired sound.

Why Bassists Love It

Traditional octave pedals can struggle with low-end definition, and many envelope filters boost the volume unexpectedly. The Docta Philter keeps your low end intact while letting you sculpt your sound in real time — perfect for slap funk, synth bass, and fusion grooves.

With the dry signal kill switch engaged, you can get pure, monophonic synth tones that sit perfectly in electronic or neo-soul mixes. Add the envelope filter on top, and you get a moving, vowel-like sweep that reacts to your playing dynamics.

Creative Uses:

• Funk Bass: Nail Bootsy-style thump with octave-down + quacky filter.
• Synth Leads: Kill the dry signal, max the filter, and play monophonic lines for a vintage synth vibe.
• Guitar Auto-Wah: Use the envelope section on its own for expressive funk rhythm parts.
• Filter-Swept Octaves: Blend the two sections for evolving textures in ambient or fusion music.
