Introducción
The DOD Overdrive Preamp 250 is a legendary analog overdrive pedal designed for guitar and bass instruments. This manual provides essential information for setting up, operating, maintaining, and troubleshooting your DOD Overdrive 250 to ensure optimal performance and longevity.
Configuración
Encendido del pedal
The DOD Overdrive 250 can be powered by a single 9V alkaline dry battery or an optional 9V DC power supply (PS0913DC). Ensure the power source is correctly connected before use.

Conectando tu pedal
Conecte su instrumento al IN jack on the right side of the pedal using a standard 1/4-inch instrument cable. Connect the AFUERA conector en el lado izquierdo del pedal a su amplifier o el siguiente pedal en su cadena de señal usando otro cable de instrumento de 1/4 de pulgada.

Operar el pedal
The DOD Overdrive 250 features two primary control knobs: GANAR y NIVEL, along with a footswitch and an LED indicator.

Figura 3: Front Panel Controls. The Gain and Level knobs are at the top, with the footswitch and LED below.
Controles
- GANAR: This knob controls the amount of overdrive or distortion applied to your signal. Turning it clockwise increases the saturation, ranging from a subtle grit to a full, aggressive grind.
- NIVEL: This knob adjusts the overall output volume of the pedal. It can be used to match the bypassed signal volume, or to provide a significant boost for solos or to push your amplifier harder. With the Gain set low, increasing the Level can provide a clean boost.
Interruptor de pedal e indicador LED
The large footswitch activates or bypasses the effect. When the effect is active, the crisp blue LED indicator will illuminate, providing clear visual feedback of the pedal's status.

True bypass
The DOD Overdrive 250 features true bypass circuitry. This means that when the pedal is disengaged (effect off), your guitar's signal passes directly through the pedal without any electronic interference, preserving your original tone. This is a significant improvement over older designs that could color the bypassed signal.
Mantenimiento
Reemplazo de batería
If using a 9V battery, replace it when the LED indicator dims or the pedal's performance degrades. To replace the battery, carefully remove the bottom plate of the pedal. Disconnect the old battery and connect a new 9V alkaline battery, ensuring correct polarity. Securely reattach the bottom plate.
Limpieza
Wipe the pedal's exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish and internal components.
Almacenamiento
When not in use for extended periods, disconnect the power supply or remove the battery to prevent leakage and preserve battery life. Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures.
