The Boomster mk.2 comes loaded with:

• selectable true or buffered bypass via internal dip switches (ships in buffered bypass mode by default)
• an expression pedal input to use as a volume pedal
• 3 minutely tuned voicing options
• momentary / latching operation
• 9-18V power-input range for variable headroom

Booster function:
Get up to  16db of clean unadulterated boost. Place the Boomster mk.2 after your drive section for a volume increase or hit the front end of your amp or different drive pedals to introduce an added gain-staging option! The 3 voicing options available are designed to help you precisely sculpt your tone and match different guitars, pedals and amps to one another.

We have carefully tuned these to a guitar-friendly range but have tested them to be useful with all sorts of instruments:
• the top position attenuates the top end (control by how much via set-and-forget internal trimmer)
• the middle position retains a flat, full-range response

• the bottom position introduces more mids (control by how much via set-and-forget internal trimmer)

*When the Level knob is all the way to the left (closed) the Booster’s output level is at unity gain.

BUFFER BYPASS FUNCTION:

The rigorous R&D process employed for the development of the
buffer inside the Boomster mk.2, accomplished the 2 main traits we feel make for a great buffer;
With the Burr Brown® OPA 2132 chip powering the buffer the Boomster mk.2 will:

• instantaneously bring back frequencies compromised over long signal chains, without the unwanted top-end harshness and compromised mids many buffers suffer from.
• successfully retain the original feel of the instrument, something very few buffers achieve.

VOLUME PEDAL FUNCTION:

Pair the Boomster mk.2 with any commonly available 10k passive Expression pedal and you have yourself a smooth travelling volume pedal starting from OFF at the heel position all the way to wherever it is that you have the L (level) knob set if the pedal is activated, or from OFF to unity gain when the pedal is disengaged and in buffered bypass mode!
