3. Controis e conexións
Figura 3.1: Panel frontalview
This image displays the main controls of the pedal: the Gain knob (left), Level knob (right), the three-position mode toggle switch (Silicon, Ge/Asym, Lift), the footswitch, and the neon yellow-green LED indicator.
Figura 3.2: Conexións do panel lateral
This image highlights the 1/4" instrument input jack on the right side of the pedal and the 1/4" instrument output jack on the left side.
Botón de ganancia:
Controls the amount of overdrive or distortion applied to your signal. Turning it clockwise increases the gain, leading to more saturated tones.
Botón de nivel:
Adjusts the overall output volume of the pedal. Use this to balance the pedal's volume with your amplifier's clean signal or to provide a volume boost.
Mode Toggle Switch:
A three-position switch that selects the clipping mode of the pedal:
- SILICON (Up Position): The classic DOD 250 sound, offering a smooth, symmetrical clipping characteristic.
- Ge/ASYM (Middle Position): Utilizes a vintage Germanium diode for an asymmetrical clipping, producing a different harmonic texture and a warmer, more compressed feel.
- LIFT (Down Position): Bypasses the clipping diodes entirely. In this mode, the pedal acts as a clean boost at lower gain settings, or a "dirty boost" as the LM741 op-amp clips at higher gain settings, adding a unique character without traditional diode clipping.
Pedal:
Engages or bypasses the effect. When the LED is lit, the effect is active. When the LED is off, the pedal is in true bypass mode, allowing your instrument's signal to pass through unaffected.
Indicador LED:
A neon yellow-green LED that illuminates when the pedal is active and the effect is engaged.
Input Jack (1/4" Instrument):
Connect your instrument (guitar, bass, etc.) to this jack using a standard 1/4" instrument cable.
Output Jack (1/4" Instrument):
Conecte este conector ao seu amplifier's input or to the next pedal in your signal chain using a standard 1/4" instrument cable.
Power Input (2.1mm DC Barrel Jack, Tip Negative):
Connect a 9V DC power supply (not included) to this jack. Ensure the power supply is tip-negative. The pedal can also be powered by a 9V alkaline battery (not included).

This image shows the 2.1mm DC barrel jack for connecting a 9V tip-negative power supply.
4. Configuración
- Conexión de alimentación:
- For external power, connect a 9V DC (tip-negative) power supply to the Power Input jack on the rear of the pedal.
- Alternatively, to install a 9V battery, carefully remove the bottom plate of the pedal. Connect a 9V alkaline battery to the battery clip inside and replace the bottom plate.
- Conexión do instrumento:
Conecta a túa guitarra ou outro instrumento ao ENTRADA jack situado no lado dereito do pedal usando un cable de instrumento estándar de 1/4".
- AmpConexión de lifier:
Conecta o SAÍDA toma no lado esquerdo do pedal para o teu amplifier's input or to the input of the next pedal in your effects chain using a standard 1/4" instrument cable.
- Configuración inicial:
Before powering on, set the Gain and Level knobs to their minimum positions (fully counter-clockwise). Set the Mode toggle switch to the 'SILICON' position for a familiar starting point.
5. Accionamento do pedal
- Involucrar o efecto:
Press the footswitch to engage the overdrive effect. The neon yellow-green LED will illuminate, indicating the effect is active. Press the footswitch again to bypass the effect; the LED will turn off.
- Axuste da ganancia:
Xire lentamente o Ganancia knob clockwise to increase the amount of overdrive. Experiment with different gain levels to achieve sounds ranging from subtle grit to heavy distortion.
- Setting Output Level:
Axustar o Nivel knob to control the overall output volume. It is recommended to set the Level so that the engaged effect volume is roughly equal to or slightly above your bypassed signal volume, depending on your desired application (e.g., a boost for solos).
- Exploring Clipping Modes:
Experimenta co Interruptor de alternancia de modo to discover the different tonal characteristics:
- SILICON: Ideal for classic overdrive tones, offering a smooth and balanced distortion.
- Ge/ASYM: Provides a unique, warmer, and more compressed overdrive with a distinct harmonic content due to the Germanium diode. Great for blues and classic rock tones.
- ELEVADOR: This mode offers a clean boost at lower gain settings, perfect for pushing an already overdriven amplifier. At higher gain settings, the op-amp itself will clip, providing a raw, uncompressed "dirty boost" sound.
- Combining with Other Pedals:
The DOD-250-50TH can be placed at various points in your signal chain. Placing it before other distortion/overdrive pedals can stack gain, while placing it after can act as a volume boost or tone shaper for existing distorted signals.
6. Mantemento
- Limpeza: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners or solvents, as they may damage the finish or silkscreen.
- Substitución da batería: If using battery power, replace the 9V battery when the LED indicator dims or the sound quality degrades. Always disconnect input/output cables when not in use to conserve battery life.
- Almacenamento: Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
- Conexións por cable: Periodically check all cable connections for wear and tear. Ensure cables are securely plugged in to prevent signal loss or intermittent operation.
