Description

The OPFXS Dig Deep MK3 is an incredibly precise downward octave pedal that takes your guitar tone into the depths, adding deep, rich, and organic bass frequencies.

The Dig Deep Octaver is widely regarded as one of the most impressive octave pedals on the market, delivering authentic-sounding sub-octaves on the lower strings, making it ideal for generating an additional bass line while playing guitar.

With the Dig Deep MK3, OPFXS has taken the original concept to a whole new level.

This upgraded version offers significantly expanded controls, independently adjustable -1 and -2 octave levels, three different octave waveforms, low-pass and high-pass filters, and a fully adjustable tracking range across the fretboard.

You can save your custom sounds in three user preset slots.

MIDI connectivity and USB-C support allow for deeper editing through the V-UNO Editor software, providing access to additional parameters and customizable assignments for Control 1 and Control 2.

The Dig Deep MK3 stands out for its exceptionally tight and accurate tracking, making it suitable for 6-string and 7-string electric guitars, baritone guitars with different tunings, acoustic guitars, and even bass guitars.

A Bass Player at Your Feet!

Feel like your guitar could use a little more low-end power?

The OPFXS Dig Deep MK3 is here to change that!

This intelligent sub-octave generator creates a rich, precise, and powerful bass line underneath your guitar playing, without sacrificing the clarity and definition of your original tone.

The result is a massive, clean, and punchy sound that can make it feel like you’ve got a bass player playing alongside you.

The MK3 takes this concept further with extensive sound-shaping possibilities.

With five main knobs, two dedicated controls, and a clever SHIFT function, you can fine-tune virtually every aspect of your sound: octave levels, dry/sub mix, high-pass and low-pass filtering, tracking range, harmonics, and much more.

Its incredibly accurate tracking delivers excellent results whether you’re playing delicate arpeggios, chunky riffs, or full-bodied chords.

You can also store up to three presets, control parameters via MIDI, and customize your settings using the V-UNO Editor via USB-C.

Another great feature is the ability to split the outputs, sending your dry guitar signal to one amplifier and the sub-octave signal to another — perfect for running the bass frequencies through a dedicated bass amp or speaker system.

Built in Italy, the Dig Deep MK3 is a powerful, innovative, and incredibly musical pedal that feels like a natural extension of your instrument.
