User Manual

Microtubes B1K
CMOS Bass Overdrive
Controls (Front)
Level: Sets the volume of the overdriven
signal.
Drive: Sets the amount of saturation in
the overdriven signal.
Controls (Back)
Open the magnetic bottom lid to access
the controls.
Blend: Mixes the clean input signal with
the overdriven signal. The clean signal is
fixed at unity gain, while the volume of
the overdriven signal is set by the Level
knob, allowing for fine control of the
blend ratio. Turn clockwise to blend in
the clean signal.
Tone: Controls the high frequency
content of the sound. A variable low pass
filter from 3 kHz to 8 kHz. Turn CCW for a
brighter sound.
DIP switches
Grunt: Provides a low-end boost to massively thicken your sound when
engaged.
MBoost: Gives a subtle 6 dB boost from 300 Hz to 1 kHz to help you cut
through the mix.
Technical Specifications
Input Impedance 1 MΩ
Output Impedance 1 kΩ
Current Consumption ~30 mA
Voltage 9V DC (Center Negative)
Dimensions
Width 50 mm (2 in) Height 100 mm (4 in) Depth 45 mm (1.75 in)
Weight 205 g (0.45 lb)
Warning
The Microtubes B1K has a current draw of 30 mA. Only use a regulated
9V DC adapter with a center-negative plug. Due to ecological reasons it
does not accept batteries. Unregulated power supplies and/or higher
voltages may result in suboptimal noise performance and even damage
your unit, voiding the warranty.
