USER MANUAL
Microtubes B3K
Little dude, Big attitude
An intuitive format that contains brutality and clarity at the
same time is what the B3K delivers. A defined and powerful
overdrive, with a simple layout gives no limits and set no rules
to unleash the desired tone.
Warning
The Microtubes B3K has a current draw of 20mA. 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.
