The Microtubes B7K 10th-Anniversary Edition is a limited edition bass overdrive pedal, designed as a tribute to the original Microtubes B7K and a celebration of its impact on bass players. It serves as a versatile tool for shaping bass tone, offering both saturation and comprehensive EQ control.
Function Description
The Microtubes B7K is primarily an overdrive pedal for bass guitars, designed to allow bass players to "cut into the mix." It provides a range of saturation levels, from subtle warmth to aggressive distortion, combined with a powerful four-band equalizer and blend control to mix the clean and overdriven signals. The pedal also features a balanced output, making it suitable for direct connection to PA systems or studio mixing consoles.

Usage Features
The pedal offers a comprehensive set of controls to sculpt the bass tone:
- Level: Sets the overall volume of the overdriven signal.
- Drive: Controls the amount of saturation, allowing users to dial in anything from a slight grit to heavy distortion.
- Blend: Mixes the clean input signal with the overdriven signal. The clean signal maintains unity gain, while the overdriven signal's volume is set by the Level knob, enabling precise control over the blend ratio. This feature is crucial for retaining the low-end clarity and punch of the original bass tone while adding overdrive.
- Grunt (G): A three-way switch that sets the amount of low-frequency content to saturate. It allows selection between three different bass boost levels before the clipping stage, influencing how the low end reacts to the overdrive.
- Attack (A): A three-way switch that sets the amount of treble content to saturate.
- Boost: Emphasizes treble content for extra clarity and presence.
- Flat: Leaves the treble register untouched.
- Cut: Reduces the amount of high frequencies being saturated.
- Low (EQ): Provides a +-12dB boost or cut at 100Hz, allowing for precise control over the sub-bass and low-mid frequencies.
- Low Mid (EQ): Provides a +-12dB boost or cut at 1kHz, affecting the fundamental body and punch of the bass tone.
- High Mid (EQ): Provides a +-12dB boost or cut at 2.8kHz, influencing the presence and growl of the bass.
- Treble (EQ): Provides a +-12dB boost or cut at 5kHz, controlling the brightness and articulation of the sound.
- Balanced Output: A balanced version of the 1/4" output, which is particularly useful for connecting the pedal directly to PA systems or studio mixing consoles without the need for an additional DI box, ensuring a clean and strong signal.
Maintenance Features
- Power Supply: It is critical to use a regulated 9V DC adapter with a center-negative plug. Using unregulated power supplies or higher voltages can lead to suboptimal noise performance and potentially damage the unit, voiding the warranty. The pedal does not support batteries.
