Finally, you can build your own high-definition multi-effects processor!

Buy the kit, build it using our very detailed instructions, download the free/open-source software, then Rock on!

A good soldering iron with fine tip and decent soldering skills are required. You will be rewarded with a super configurable and customizable processor that rivals many $450+ commercial units.

The Software

The recommended install contains over 600 plugins - effects, simulators and sound generators (synths playable via MIDI).

Connect your computer via wifi, then through a browser, using the intuitive drag-n-drop MOD UI webapp, create/edit numerous virtual pedalboards containing up to a dozen or so simultaneous plugins with very flexible signal routing.

Once your pedalboards are saved, only the pi Stomp is needed on-stage, or in the studio or bedroom.

Pedalboards can be controlled in realtime by attaching an external MIDI controller or by adding onboard controls.

Possible Hardware Customizations (using supplied pluggable headers)

• Connect up to 8 analog controls (pots, faders, expression pedals, switches, sensors, etc.)
• Extra switches. Kit comes with 3 footswitches but you can add up to 5 more.
• Add TRS MIDI. USB MIDI is always available, if you need DIN MIDI, just add an optional $14 module.

The pi-Stomp Core Kit includes everything to build a working system

• pi-Stomp Core circuit board (v2.0.4)
• All board components (resistors, caps, transistors, relay, jacks, headers, volume pot, encoder, IC's and sockets)
• A sturdy die-cast aluminum powder coated enclosure pre-drilled with UV printed labeling (color is Laser Burgundy)
• IQAudio Codec Zero audio card
• Raspberry Pi 3 A+
• Hat Hacker board
• 2.2" TFT LCD 240x320 Color Display
• Standoffs and screws
• Micro SD Card (32GB, Class 10)
• 2 tweak pots, volume pot, navigation encoder and 4 knobs
• 3 high quality footswithes
• 3 different colored LED footswitch halos
• Female/Female Jumpers for attaching common peripherals
• Power Supply: Low noise, 5v, 2Amp with 2.5mm barrel connector. Universal voltage input with NEMA 1-15P (aka USA) blades. Mechanical adapter required for connection in other countries.

The kit does NOT include

• DIN MIDI In/Out or Expression pedal input. Midi+Expression add on kit available via Treefallsound This kit does not include drilling of the extra holes for the Midi+Expression module, so if you want that, you would be better off ordering the kit directly from treefallsound.com
• A power switch. We recommend powering via a powerstrip.
• Tools, solder, etc.
