Mini OD-503
Low-gain dynamic overdrive that cleans up with your volume knob. Handmade mini format.
The Mini OD-503 is a dynamic amplifier overdrive that enhances your instrument's natural harmonic content without heavy coloration. Low-gain circuit with minimal compression—designed for guitarists who want extra saturation and bite while preserving picking dynamics. Cleans up beautifully with either pick attack or guitar volume control.
Three controls: Output (volume), Treble (passive high-frequency rolloff for smoother tones), and Drive (gain amount). The circuit gives you more of your instrument and amp rather than imposing its own character. Input impedance ~500KΩ, output impedance ~20KΩ.
True bypass, daisy-chain friendly. 9VDC center-negative, <60mA. Ultra-compact mini enclosure. Handmade in Portland, Oregon using premium components.
