The Micro Booster MK4 Onboard Guitar Preamp is designed to amplify the magnetic pickup signal and provide a selectable boost that can be quickly engaged for solo performances. The built-in two-band equalizer facilitates subtle tonal adjustments and offers a range of boost modes including Clean Flat Boost, Mid Boost, Treble Boost, Boosted V-Cut, among others, that can be tailored to suit specific preferences or practical requirements.
The Boost Knob
From buffer level up to +16dB of clean boost with gentle Baxandall EQ and Push-Push True Bypass.
The BECOS Micro Booster MK4 Onboard Guitar Preamp can be easily installed in any guitar or bass to amplify the signal from passive magnetic pickups. It can be powered using a single 9V standard alkaline battery or two batteries connected in series for 18V increased headroom. The booster is activated when the instrument cable TS mono plug is inserted into the instrument output, and it has very low power consumption, allowing it to run for months. It is recommended to remove the instrument cable when not in use to conserve energy.
The Micro Booster MK4 utilizes high-performance monolithic amplifiers that deliver pristine audio quality with an exceptional frequency response and extremely low noise and distortion.
A tone correction stack adds flexibility for independent tonal adjustment of Lows and Highs, offering mild adjustability of +/-6dB at 70Hz and 3.5KHz and zero to +16dB variable general Gain. This allows for configurations such as Clean Flat Boost, Mid Boost, Treble Boost, Lows Boost, Boosted V-Cut, and more, without going to extremes. The boost is completely flat when the tone knobs are centered, and it acts as a silent high-quality buffer when the gain is set to zero.
The Micro Booster MK4 can be configured with a linear B500K switch-pot (used with humbuckers) or with a linear B250K switch-pot (used with single coils), which will be pre-soldered directly on the circuit board. The potentiometer side of the switch-pot only replaces a potentiometer in your instrument (volume or tone), while adding the convenience of a signal routing switch on top of it. The mechanical PUSH-PUSH switch side of the switch-pot routes the signal through the booster (switch UP) or sends it True Bypassed straight to the output (switch DOWN).
A board-only version is also available if you wish to add the Micro Booster MK4 alone, without replacing a potentiometer in your instrument. In such installations, a separate DPDT switch (not included) needs to be wired for signal routing.
An iron-made shielding covers the entire active circuitry to protect it against radiant electromagnetic interference.
Several shortcut points are added on the circuit board to eliminate the usage of some wires when reconnecting the replaced potentiometer. Insertion points are also available for a neat transfer of the guitar Tone Capacitor directly on the booster’s board if the booster is to be placed on top of a tone potentiometer.
The basic interconnecting wires, battery holder, battery clip, and a new TRS output connector are supplied along with the uBST4 board and the desired Push-Push switch-pot.
The Micro Booster MK4 is pin-compatible with MK3.
