Soundsketch Digital MultiEffect

The Soundsketch is a SMD (surface mount) open source digital guitar pedal platform developed by GuitarML (based on a modified version of the DaisySeedProjects 125B pedal) and designed around the very capable Daisy Seed chip by Electro-Smith. It features buffered stereo input and output, as well as expression and midi input via full size 1/4" TRS jacks. The project scope includes having a pcb manufactured (JLCpcb or PCBway recommended), soldering and assembling the pedal, and uploading the effects software. GuitarML doesn't sell kits, it is truly a "Do It Yourself" kind of project. Several of the Funbox modules have been ported to Soundsketch, as they share the same basic controls, minus the dip switches. A major improvement over the Funbox is no noise. SMD design, 4 layer with internal ground shielding, and spacing of analog and digital sections contribute to the noise reduction.

TouchedOut Synth and Sampler

The TouchedOut Synth / Sampler is not a pedal, but a capacitive touch synth on a single PCB. It uses Adafruit modules for MPR121 capacitive touch, joystick, controls, and Daisy Seed for digital processing. It was developed using the Arduino IDE, and is a great entry to using DaisyDuino for embedded music. The hardware PCB is open source in KiCad and can be ordered from a manufacturer such as JLCpcb or PCBway. The firmware is open source and comes in two flavors: Synth or Sampler. The Synth is a subtractive synth with effects and looper. The Sampler is a chromatic sampler (via additional microphone) and looper with effects.

Funbox Digital MultiEffect

The FunBox is an open source digital guitar pedal platform developed by GuitarML and designed around the very capable Daisy Seed chip by Electro-Smith. It features buffered stereo input and output, as well as expression and midi input via 1/8" TRS jacks. Its design and effects were inspired by high-end audio brands such as Meris, Chase Bliss, and NeuralDSP. GuitarML has developed a suite of open source effects available on Github, including a neural amp sim, reverb/delay, dual looper, FFT based spectral reverb and delay, and a Midi keyboard synth. The project scope includes ordering the Funbox through-hole PCB, electronic components, and enclosure, soldering and assembling the pedal, and uploading the effects software. GuitarML doesn't sell kits, it is truly a "Do It Yourself" kind of project, however I have a comprehensive build guide and resources to assist. Whether you dream of creating your own commercial grade digital effects, looking for your next STEAM project or an addition to your pedalboard, the Funbox is a great place to get started.

Seed Pedal

The Seed pedal is an open source digital guitar pedal designed around the Terrarium platform by PedalPCB (which uses the Daisy Seed chip by Electro-Smith). It is a mono multi effect including 4 neural amp models, reverb, delay, tremolo, and a 5 minute reversible looper. Note: Due to updates in the Daisy Seed chip, modifications to the original Terrarium are required for noise reduction. See notes on Github project page Readme.

Analog Pedals

If analog pedals are more your thing, GuitarML does that too! Currently we have an open source design for a simple boost pedal perfect for getting into DIY pedal building. For a more advanced analog pedal, there is a dual Tubescreamer / Rat with independent lighted footswitches and an order toggle.

Daisy Seed Projects Pedal

This pedal is a Daisy Seed based pedal by Github user bksheperd (not GuitarML), with open source hardware that anyone can build for themselves. This is a high quality SMD design with stereo, quiet relay bypass, an OLED screen and tons of controls. GuitarML has developed a collection of effects for the platform. Visit the github project page for more info, and watch the GuitarML demo video to get an idea of what it can do.
