The Oneder Old Blue is a low to medium gain overdrive that’s transparent but can get very saturated and even heavy via the interaction of the Level and Gain knobs (on the top) with the Weight one (bottom right), which adds girth and saturation.

The clipping switch in the center of the case provides two voicings, a smoother/vintage one and a more modern and open one, further widening its tonal palette. The other knob on the bottom left is Range, which controls the amount of treble.4
