The Microtubes 500 is a 500W amplifier equipped with an all analog solid state preamplifier and a Class D Power Module.

On the top row, you will find the clean section which is the foundation of your tone. It features a Gain control and an active 4 band EQ: along with Low and Treble controls, you will find Low Mids and Hi Mids controls, each knob with their own 2-way frequency switch.

On the bottom row, you will find the Microtubes Engine, an extra channel that will bring your clean tone to the next level by helping you cut through the mix while adding anything from subtle, tube-like, harmonics and natural compression to obliterating distortion.

• Passive/ActiveSwitch from passive to active mode. Some active basses can have a hotter signal output which can make the amplifier distort early (feel free to use it on Passive mode even with active basses if such additional distortion is desired).
• MicrotubesEngages the Microtubes Engine to add natural compression, organic harmonic enhancement, and saturation ranging from mild overdrive to high gain bass rage. The Microtubes Engine operates before the clean section
• ToneControls the high harmonic content of the Microtubes Engine via a variable low pass filter: crank it up for additional attack and definition or dim it down for a smoother sound. This is handy when running bright EQ settings or cabinets with tweeters.
• BlendMixes between the Clean and Distortion signals (Microtubes Engine).
• B3K/VMTSelects between two overdrive circuits: B3K mode will deliver an aggressive, percussive sound while the VMT will bring up the mids for a warmer, more neutral character.
