Microtubes 200

Front Panel Features
INPUT: Use this jack to connect your instrument via a standard ¼” mono cable.
MICROTUBES: Use the Microtubes B3K® Engine to add natural compression, organic harmonic enhancement, and saturation ranging from mild overdrive to high gain bass rage. The Microtubes B3K® Engine operates before the 4 band EQ section (so you can use the EQ for additional tone shaping).
DRIVE: This knob controls the amount of distortion that the Microtubes B3K® Engine will deliver. It will change from a soft warm overdrive to a massive modern distortion sound.
BLEND: Use this knob to mix between the Clean signal and the Distortion signal (Microtubes B3K® Engine).
BASS: +-12dB at 80Hz. Use this knob to change the low-end content of the signal.
LOW MIDS: +-12dB at 1kHz. This knob controls the low mid content of the signal.
HIGH MIDS: +-12dB at 3kHz. This knob controls the high mid content of the signal.
TREBLE: +-12dB at 5kHz. Use this knob to change the high content of the signal.
MASTER/MUTE: Use this knob to control the overall volume of the ampliﬁer. Use this push knob button to mute the ampliﬁer.

Warning

There are no user-serviceable parts inside the ampliﬁer. Do not open the amp.
Never use the amp in a high moisture environment or near liquids.
The Microtubes 200 can deliver more than 100 dB of power.
Exposure to this level of sound can damage your hearing.
Always use proper hearing protection when exposed.
The Microtubes 200 can deliver more than 200 watts. Be sure that your speaker cabinet is able to deliver that power.
Do not cover the vent holes. The fan and vent holes are part of the cooling system of the amp. Covering the vent holes can lead to overheating and damage to the ampliﬁer.
Do not use an instrument cable as speaker cable. An instrument cable is not designed to deliver the type of power sent from the ampliﬁer to the speaker.
