David Cardona

Sound Designer – Composer – Audio Engineer

At Pueblo FX, we like to recognize the talent that supports our vision. Today we are featuring our friend and go-to engineer, David Cardona. He has used our very first pedal Raíz in many of his productions and mixes, including his latest artistic statement Implode under the moniker 28 Lines. In this post, we’d like to share David’s approach to using Raíz in enhancing this composition.

David is from our motherland, Colombia, and we’ve known each other for many years. We saw each other’s passion grow from sharing records, into creating devices that make records, and actually making records. At Pueblo FX, we’re lucky to count on his support and skill when testing new prototypes. He also records samples for you to hear so that you can be confident before choosing to bring your hard earned buck into our shop. Together, we conceive new ideas based on what we feel could enrich our own music. We back our ideas with our experience as audio designers and engineers, and combine it with our ever-evolving passion for bringing the gems of new and old technologies to artists, so they shape the future of sonics!

We feel honored to know our pedal is contributing to the making of timeless records and good music. Since he started his own company, Sound Architect, David continues to bring our signature sound into his mixing tool arsenal. Our very own Raíz has been used in a good portion of David’s discography, including Bombino’s grammy-nominated record Deran, Odd Behavior by the evocative Indie-rock band Oddysseys, Labyrinths and Tales by our featured artist and drummer Clemens Grassmann, and Patch’d by the groove-box machine that Color Channel has prepared.

Our Raíz pedal was also use by David in his most recent composition and production, under his electronic music project 28 Lines. David worked with record label Music Dribble Entertainment to release and market Implode. The debut single has been well received, making waves among audiences and receiving coverage from numerous publications. The song is an extremely visual composition, exploring many sound design and audio engineering concepts, all in a cinematographic context that surrounds and immerses the listener. It is a meticulously organized yet organic composition, brought together as if purely by chance. David has referred to this composition as his playground to learn and bring nuanced sound design techniques into a scenario that maintains the music first, with ear candy only enhancing the experience. The Raíz’s booster and screamer tones can be heard in several layers of the song, from the rich and subtle saturation of the bells and ambiances, to the aggressive bass hits and stutters that rip through the audio field. We especially enjoyed Implode’s use of distorion, balancing the subtle and the aggressive, and look forward to the new releases 28 Lines is crafting for all of us.

On the track Implode David implemented the Raíz pedal by using parallel processing, which he refers to as his go-to technique. For instance, the pedal was set after a reverb plug-in in an ambiance chain, in the boost setting, to enhance the textures instruments are generating, and bring up the quietest moments in the reverb’s output. This boost can be presently heard in the trails of reverb coming from the toy piano that performs at the opening and closing of the song. The distortion settings, with dip switch settings 1-3-6 and 4-7, were used in parallel layers (followed by a compressor listening to the dry signal via side-chain input) in the main synth bass, and sawtooth synth in the A sections. With these settings and this chain, the result is distortion peaking out when the amplitude of the dry sound lowers below the compressor’s threshold. Both source sounds for these synths have been confirmed by David to come from Spectrasonics’ Omnisphere 1 library. In these cases, the tone of the Raíz was set to the 12 o’clock and 2 o’clock positions, and drive at 10 o’clock and 1 o’clock respectively. The volume knob was adjusted to get the same levels when the pedal is both bypassed and engaged. These are just a few ways in which our little pedal has broken through conventional mediums and penetrated the creative aspects of the music production world. We won’t give away too much, and let you experiment on your own!


At Pueblo FX, we are always working, with David and other artists, on functional and innovative tools and devices to boost your creativity.

You have become a part of our family when you plugged in for the first time your instrument right into our very first pedal Raíz. So please get in touch! Get involved! Send us suggestions! Let us know what you thought of our Raíz and what you would like to see us build next!

We thank you deeply for supporting us and truly wish that our efforts have helped enhance your music and shape your tone.
