DISTORTION
X Type:
Build Level: Intermediate
Based On: Nobels® ODR-S™
If you are a fan of the Nobels® ODR-1™, you'll no doubt like its cousin the ODR-S™. The addition
of a three-band EQ offers more tonal range. The germanium clipping diodes makes for a thicker
and more compressed overdrive/distortion than offered by the ODR-1™.
•
LEVEL: Total effect output.
•
GAIN: From moderate to heavy distortion.
•
BASS/TREBLE: Active Baxandall style controls which allow for boost or cut in the bass and
treble frequencies.
•
MIDS: Ranges from mids scoop (CCW) to mids boost (CW) by way of a gyrator.

These were used to avoid motorboating when the Gain and Bass knob are maxed. Thanks to Kevin at AION FX for helping me to solve this issue on my prototype build! •...
