Indledning
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.
Opsætning
Styring af pedalen
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.

Tilslutning af din pedal
Tilslut dit instrument til IN jack on the right side of the pedal using a standard 1/4-inch instrument cable. Connect the UD stikket på venstre side af pedalen til din amplifier or the next pedal in your signal chain using another 1/4-inch instrument cable.
Figur 2: Input and Output Jacks. The input jack is on the right, and the output jack is on the left.
Betjening af pedalen
The DOD Overdrive 250 features two primary control knobs: GEVINST og NIVEAU, along with a footswitch and an LED indicator.
Figur 3: Front Panel Controls. The Gain and Level knobs are at the top, with the footswitch and LED below.
Kontrolelementer
- GEVINST: 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.
- NIVEAU: 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.
Fodkontakt og LED-indikator
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.

Ægte 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.
Opretholdelse
Udskiftning af batteri
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.
Rensning
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.
Opbevaring
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.
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen lyd eller svagt signal | Incorrect cable connections, dead battery, faulty power supply, pedal not engaged. | Check all cable connections. Replace 9V battery or verify power supply connection. Ensure the pedal is engaged (blue LED on). Test with different cables. |
| Uønsket støj eller brummen | Ground loop, faulty cables, interference from other electronics, power supply issues. | Ensure all equipment is properly grounded. Try different cables. Move pedal away from power transformers or fluorescent lights. Use a regulated power supply. |
| LED lyser ikke | No power, dead battery, faulty LED. | Check power supply or replace battery. If problem persists, contact support. |
