Chopper Party Device – Eagle and Gerber Files

Product Format Clarification

This product includes digital design files only — no physical PCB is shipped.

With these files, you can order PCBs directly from a manufacturer (e.g., JLCPCB, PCBWay) for as little as $2 for 5 boards.
Typical production time is 3 days, and international shipping starts at $12, taking about 4 days via DHL to most locations.

You’re free to edit the design and add your own branding.

Upon Purchase, You’ll Receive:

• Eagle CAD files (.SCH & .BRD) — fully editable and compatible with KiCad

• Industry-standard Gerber files for PCB fabrication

• Quick-start guide explaining how to use the files

• Download link for the free version of Eagle CAD

After purchase, you will receive a payment link by email. Once the payment is completed, the design files will be sent to you within 8 hours. We’re currently working on automating this process, but for now, orders are handled manually.

Note: You must use these files with a PCB manufacturer to produce your boards.
No pre-assembled or pre-made circuit boards are included.

These design files are intended for personal use and small production runs of your own pedals, not for resale as kits or standalone PCBs.

Project Overview

Looking for a distinctive and creative multi-effects pedal? Look no further than the Chopper Party Device!

This board is based on the custom-made EarthQuaker Devices Helicopter Party, a one-of-a-kind EQD creation named after the band Party of Helicopters.

Introduction

This is one special day for you; you just ran into a pedal that is as cool as impossible to find and believe me, it’s extremely cool! You are in the presence of a unique board that features a chain of Hoof, Grand Orbiter, and Hummingbird pedals, with expression inputs for both Hummingbird rate and Grand Orbiter rate.

Whether you’re playing a gig or just jamming in your basement, this Chopper Party Device is sure to deliver a fantastic sound. It allows you to create cool effects on the fly, combining the acclaimed muff-inspired fuzzes tones of the Hoof, the outer space sounding of the Grand Orbiter, and the choppy, sawtooth vintage tremolo of the Hummingbird board in the most amazing ways. Can you imagine that? Just connect the cables and start playing!
