INTRODUCTION
The Hadron Dynamic Overdrive is a recreation of the Lovepedal Eternity, first released in 2005. There
have been several versions of the Eternity throughout the years, with names like Burst, Fuse, Kanji,
D-Mod, and Roadhouse. However, they all have the same basic circuit. The provided parts list is based
on the original Eternity, but you should be able to build almost any version if you know what changes
to make. The differences are typically only in the component values used and the number of clipping
diodes.
Like the Zendrive, the Eternity can be seen as a stripped-down Tube Screamer, based on the original
1997 “Son of Screamer” circuit by Jack Orman. It’s essentially a Tube Screamer without input & output
buffers. This makes it interact better with a guitar’s volume & tone knobs, but on the flip side it also
interacts with the pedals that come before & after.
Alongside the Azimuth, the Hadron has among the lowest parts count of any Aion FX project and is a
very good starting point for new builders.
USAGE
The Hadron has the following controls:
•
Drive
controls the amount of gain in the op-amp feedback diode clipping stage.
•
Tone
controls the treble response of the effect. The center point (12:00) is flat. When turned to the
left, it cuts treble, and when turned to the right, it boosts treble.
•
Volume
controls the overall output.
