for bassO2 Oxygen Bass Preamp

The O2 Oxygen Bass Preamp is a must have on a bass player pedal board.

With its efficient and sensitive five control knobs it allows you to deliver YOUR tone – whether on stage or in the studio.

The internal “BASS BOOST” switch allows you to squeeze more bass from the O2 while the “MID SHIFT” switch allows instant selection of one of two distinct tones: deep warm and smooth, or hard, fast and responsive. Both modes are delivered dynamically and with great definition.

Every note will be sculpted with the O2 Bass Preamplifier.
