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!
