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

The Echo Nightmare is a dream come true for everyone who likes to experiment with lo-fi delays, ambient noises, and crazy fuzzes, all in one box. With seven knobs and two switches, we can assure you that this is definitely the tweakaholics dream!

This circuit allows you to build such a versatile pedal capable of experimenting with different shape of waveforms, slapback, or self-oscillating feedback, you can even use the modulation and fuzz sounds with the delay or on their own, just by flicking the dry switch, making this circuit way more versatile than any

other delay pedals.

Introduction

The circuit of the Echo nightmare is as crazy as the tones it generates; like always, we could not expect less from the people from DBA.

The most interesting part of this circuit is, without a doubt, the XR2206P IC in charge of changing the shape of the wave, controlling depth and speed of the modulation. Definitely a unique approach for a modulated delay.

We included an internal charge pump over the original design that provides the XR2206P with 18v for the right functioning.

Every time you face a Death by Audio pedal you are in front of a challenge!

For this case, we have this fuzz-reverb-delay-noise machine featuring a pt2399, one dual opamp (MC3372 on the original, could be replaced by more common ones), one discontinued and hard to find XR2206, plus an internal voltage duble in charge of feeding this circuit with the right voltage!

In this first prototype, there was a missing capacitor in the front; you just need to wire it in between the 3pdt and the IN pad. Plus, an external wire as present in the picture of the final build!
