A high-end booster that allows volume control with an EXP pedal. The high headroom provides an overwhelming sound projection that boosts the amplifier's range without losing any of it's feel. This is a compact, professional booster with excellent user options and a wide range of user capabilities. With its musical response and increased headroom, the Boomster mk.2 sets a new standard for buffers and boosters. After extensive testing and comparison with currently available chips, we selected the hi-fi grade Burr-Brown OPA 2132 chip for optimal performance. This results in ample tonal range and a rich sound. Equipped with features and refined features to meet the demands of modern musicians, this boost pedal is an essential tone component for any rig. [About the included functions] - True bypass or buffered bypass selectable via internal dip switch - Expression pedal input (can be used as a volume pedal) - 3 voicing options - Momentary/latching operation -9-18V power input range allows variable headroom ■Booster function: Provides extremely clear boost sound of up to 16dB. Place the Boomster mk.2 after a drive section to boost volume, or push a drive pedal or amp to create an additional gain stage. Three voicing options let you precisely tailor the tone of your boosted sound, designed to match a variety of guitars, effects, and amps. - Up position: Attenuates high frequencies (adjustable with internal trimmer) - Center position: Maintains a flat full-range response - Down position: Emphasizes mid-range (adjustable amount with internal trimmer) *When the Level knob is fully to the left (turned down), the output level of the Booster is at unity gain. Volume Pedal Function: When combined with a commercially available 10k passive expression pedal, it can be used as a volume pedal. When the effect is on, the volume increases from off (heel down) to the position set by the L (Level) knob. When the effect is off and in buffered bypass mode, the volume can be adjusted up to unity gain.■Specifications 1.
