3.1. Styringer
- Niveau: Controls the overall output volume of the pedal.
- Køre: Adjusts the amount of gain for the distorted high-pass signal.
- Blande: Blends the clean low-pass signal with the distorted high-pass signal. Fully counter-clockwise is 100% clean, fully clockwise is 100% distorted.
- Mellemtoner: An active mid-range control with ±12dB of boost or cut at 500Hz. This allows for significant tonal shaping of the overall output.
- Lavpasfilter (LPF): Selects the cutoff frequency for the clean signal path. Frequencies below this setting are passed through clean. Adjustable from 50 Hz to 500 Hz.
- Højpasfilter (HPF): Selects the cutoff frequency for the distorted signal path. Frequencies above this setting are sent to the distortion circuit. Adjustable from 100 Hz to 1 kHz.
3.2. Forbindelser

- Input: Connect your instrument (bass guitar) here using a standard 1/4" instrument cable.
- Produktion: Forbind dette med din amplifier or audio interface using a standard 1/4" instrument cable.
- 9VDC: Power input for a standard 9V DC power adapter (center negative). Ensure the power supply meets the pedal's requirements.
- XLR DI Output: (Rear Panel) Provides a balanced output for direct connection to a mixing console, audio interface, or PA system. This output is ideal for recording or live sound applications.
4. Opsætning
Follow these steps to set up your Darkglass Microtubes X pedal:
- Sørg for din amplifier and other audio equipment are turned off.
- Connect your bass guitar to the Input jack of the Microtubes X pedal.
- Tilslut Produktion jack of the Microtubes X pedal to the input of your amplifier or desired audio device.
- Connect a standard 9V DC (center negative) power adapter to the 9VDC input.
- If using the DI output, connect an XLR cable from the XLR DI udgang to your mixing console or audio interface.
- Once all connections are secure, you may power on your amplifter og andet udstyr.
5. Betjeningsvejledning
The Microtubes X pedal's unique design allows for precise control over your distorted bass tone. The signal is split into two paths: a clean low-pass signal and a distorted high-pass signal. These are then blended together.
5.1. Achieving Your Tone
- Start with Filters: Begin by setting the Lavpasfilter (LPF) og Højpasfilter (HPF). The LPF determines the upper frequency limit of your clean low-end, while the HPF determines the lower frequency limit of the signal that gets distorted. Experiment with these to find the sweet spot where your low end remains clear and punchy, and your high end gets the desired grit.
- Dial in Drive: Juster Køre knob to control the intensity of the distortion applied to the high-pass signal. Higher settings will yield more aggressive and saturated tones.
- Blend the Signals: Brug Blande knob to blend the clean low-pass signal with the distorted high-pass signal. This is crucial for maintaining bass clarity while adding distortion. A common starting point is around 12 o'clock, then adjust to taste.
- Shape with Mids: De Mids control allows you to boost or cut the mid-range frequencies at 500Hz. This can help the bass cut through a mix or provide a more scooped sound.
- Set Overall Level: Brug endelig Niveau knob to set the overall output volume of the pedal, ensuring it matches or exceeds your bypassed signal level as needed.
The footswitch engages or bypasses the effect. When engaged, the LED indicator will illuminate.

| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen lyd når pedalen er trådt i. | Incorrect power supply; faulty cables; incorrect connections; pedal not receiving signal. | Verify power supply (9V DC, center negative); check all cables for damage and ensure they are fully inserted; confirm instrument and amplifier fungerer korrekt. |
| Uønsket støj eller brummen. | Ground loop; faulty power supply; interference from other electronics; dirty power. | Use an isolated power supply; try a different power outlet; move the pedal away from other electronic devices; check for faulty cables. |
| Distortion not engaging or sounding weak. | Drive knob too low; HPF set too high; Mix knob favoring clean signal. | Forøg Køre knob; lower the Højpasfilter (HPF) frequency; adjust the Blande knob towards the distorted side. |
If the issue persists after trying these steps, please contact Darkglass support for further assistance.
