The Gallien-Krueger MB-200 Ultra-Light 200 Watt Bass Amplifier Head is a lightweight and compact powerhouse that offers incredible power in an easy to transport design. Whether you're practising at home, jamming with friends, hitting the studio or taking to the stage, this little beauty is the perfect performing companion.
Tiny Footprint, Masses of Power
The MB Series of amplifiers benefit from a ground-breaking amp design that packs incredible power into a tiny chassis. With a solid state preamp and a digital power amp, every effort has been made to ensure flawless signal integrity throughout the entire amplifier circuit. Boasting a 200-Watts output at 4 Ohms, and 140-Watt at 8 Ohms, you easily have more than enough power to pack a serious punch. The Class D power supply runs very efficiently, with a continuously variable fan cooling design that responds to the temperature of the circuitry to minimise fan-noise at low levels, and maximise cooling power at high levels.
Variable Pad Switch and Clip Indicator
Next to the standard jack input you'll find the -10dB On/Off switch, which allows you to pad the input when using active pickup equipped basses. Alternatively, if you're using a passive pickup equipped bass, simply turn the switch off again. The pad button flashes red when the input is overdriven.
Gain and Contour Controls
The Gain control allows you to set the preamp gain following the input stage, which can be used alongside the input pad control to optimise the amplifier's headroom. The Contour switch works in conjunction with the active equalization, by decreasing the mid-range frequencies while boosting low and high frequencies.
The MB-200 is equipped with a four-band EQ section with controls over: Bass, Low-Mid, Hi-Mid and Treble. The Bass control allows you to boost or cut around 60Hz by +10dB, delivering a fatter and looser response or a tighter low-end sound. The Low-Mid control boosts and cuts around the 250Hz +6dB/-10dB, which allows you to soften the lower-mid range or create more saturation. The Hi-Mid control boosts and cuts at the 1kHz range, which allows you to hone in on your lower string harmonics to deliver greater punchiness to your tone. The Treble control boosts and cuts at 7kHz, which allows you to soften the upper frequencies and remove high-end pop or definition, particularly useful for when you want to temper your slapping technique's response.
Along the rear panel there are a range of connections including: a Direct Output (XLR) that allows a balanced output to be sent directly to a P.A. system with a standard microphone cable; an Aux In (1/8-inch jack) for connecting an external audio source; a Headphone/Line Out/Chain Out jack with a switch that allows you to send a direct (unbalanced) line output to an unbalanced input. The Chain output enables connection to a Gallien-Krueger MBP powered extension cabinet. The Headphone output allows you to silently monitor your playing for quiet practise. The Speaker output allows you to output directly to a speaker cabinet.
The Gallien-Krueger MB-200 Ultra-Light 200 Watt Bass Amplifier Head is a fantastic bass amplifier head that is a dream come true - easy to carry around, built like a tank, and sounds fantastic.
