You have acquired an unusual tool. The perfect combination of brutality and clarity, B3K Microtubes deliver defined, powerful saturation in an intuitive format. There are no rules or limits, so dig in and free your tone.
Level Adjusts the volume of the distorted signal.
Drive Adjusts the amount of saturation of the overdriven signal.
Blend Blends the clean input signal with the distorted signal. The clean signal remains at unity gain while the volume of the overdriven signal is adjusted by the Level knob, allowing precise control of the mix ratio. Grunt Switch Adjusts the amount of low frequency content to saturate by selecting between three different bass boost levels before the clipping stage. Attack Switch Adjusts the amount of treble content to overdrive: The “Boost” setting emphasizes the clarity and presence of treble content. The “Flat” position leaves this register intact while the “Cut” position reduces the amount of distorted high frequencies. This new addition helps keep the high end of the signal under control, especially useful when playing with new strings and/or speakers with tweeters! DIMENSIONS 11.3 × 7.5 cm (4.45 × 2.95 inches) CAUTION The Microtubes B3K has a current consumption of 20 mA. Use only a regulated 9V DC adapter with a negative center plug. For ecological reasons, it does not accept batteries. Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your device, voiding the warranty.
