The Gallien-Krueger MB 115-II UL 1 x 15" 200-Watt Bass Combo Amplifier takes the already incredible features included in the MB Combo series and adds some extra touches to make things even better. Alongside the responsive 15" speaker there is an additional horn, which adds greater mid to high-end clarity for an even more refined performance.
The MB 115-II features all digital circuitry to produce its impressive 200-Watt output, which gives it an enormous amount of power and dynamic range to play with. As well as this, GK has included their proprietary G.I.V.E. Technology, which stands for Gate Induced Valve Effect. GK has used field-effect devices with the gate biased to optimise harmonic content of your tone. G.I.V.E. works closely with the built-in four-band EQ to ensure exceptional performance.
In order to prevent unwanted damaged occurring, the MB Series has built-in Smart Protection Circuitry. Should anything occur whilst you're playing, the blue light on the power switch will revert to red as a warning indicator. It is also worth noting that when you initially switch on the amp, the light will turn from red to blue, indicating when it is safe to start using the amp.
Four Band EQ
The MB 115-II benefits from a versatile four-band EQ, which controls: Bass, Lo-Mid, Hi-Mid, and Treble, enabling seamless attenuation over selected frequency bands. The Bass control enables a +10dB boost or cut around 60Hz to create a much fatter low-end energy or tighten things up for a controlled low-end pop. The Low-Mid control boosts and cuts around 250Hz by +6dB/-10dB, allowing you to accentuate the depth of clarity of your overall tone.
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 punch 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 soften the response of your slapping technique.
Front Panel Controls
Across the front panel you'll find a host of controls that give you exceptional control over your signal. Alongside the instrument input is the -10dB pad switch, which can be used to prevent unwanted clipping of the input signal - particularly useful where active pickups are used. The Gain pot enables the input gain to be increased, and also works well alongside the pad switch to optimise the amp's headroom. The Contour switch scoops-out the midrange frequencies, accentuating the low-end and upper frequency ranges.
Following the EQ controls, there is a Boost pot that allows post EQ gain to be introduced to create an aggressive edge to your signal. The Master Volume control then allows you to increase the overall signal output to give your tone some serious presence. The Limiter control works had to prevent your power amp from distorting, and is great for keeping things in check when you're using active pickups. The built-in Horn control activates the high frequency tweeter, giving an added dimension to the tonal response of your playing.
The balanced direct output XLR jack connects the MB 115-II directly to a PA system, with a Pre/Post EQ button that determines whether or not the direct output signal is sent before or after it has run through the four-band EQ. The Chain Out connection on the rear of the amp allows you to connect directly to Gallien-Krueger's MBP powered cabinets, sending all amp and EQ settings.
The Auxiliary In jack, which allows you to connect an external audio source (e.g. MP3 player) so that you can practise and play along with your favourite songs. If you're performing solo, it is a great way to play with a backing track. The headphone output allows you to practise in silence, great for late night sessions at home or on the road.
The Gallien-Krueger MB 115-II UL 1 x 15" 200-Watt Bass Combo Amplifier is lightweight and easy to transport, slipping into any backline discreetly, whilst delivering a massive sound that is perfect for any performing environment.
