With its musical response and increased headroom the JAM Pedals Boomster mk.2 aims to redefine the quality standards of thebuffer and boostergenres. Extensive testing and comparison sessions with most of the appropriate chips currently in production, resulted in us opting for the hi-fi-gradeTexas InstrumentsOPA 2132 chips, which deliver effortless fidelity and lushness across the Boomster mk.2’s different functions.

Our mission with the mk.2 versionof the Boomster was to elevate itinto a well-rounded boost pedal encompassing all the necessary features and functions contemporary musicians have come to expect, as well as to offer a standalone buffer that not only sounds great but also feels right under the hands, making it an indispensable tone component of any rig.

Mission accomplished!

The Boomster mk.2 comes loaded with:

selectabletrue or buffered bypassvia internal dip switches (see schematic)
anexpression pedalinput to use as avolume pedal
3minutely tunedvoicing options
momentary / latchingoperation
9-18Vpower-input range forvariable 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 positionattenuates the top end(control by how much via set-and-forget internal trimmer)

the middle positionretains a flat, full-range response

the bottom positionintroduces 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 Boosters 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 Texas Instruments OPA 2132 chip powering the buffer the Boomster mk.2 will:

instantaneouslybring back frequencies compromised over long signal chains, without the unwanted top-end harshness and compromised mids many buffers suffer from.

successfullyretain 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 startingfrom 0db at the heel position all the way to wherever it is that you have the L (level) knob setif the pedal is activated, orfrom 0db to unity gainwhen the pedal isOFFand inbuffered bypassmode!
