PiezoZoid for Double Bass

Dedicated analog preamp and stage control system for upright bass piezo pickups

More than just impedance matching

Proper impedance matching is essential for every upright bass piezo pickup.

But on stage, players often need much more than a simple buffer.

Different pickups, different basses and different venues all present their own challenges. Excessive piezo midrange, uncontrolled low frequencies, ground loops, phase issues, effects integration and reliable connection to modern PA systems all become part of the performance.

PiezoZoid was designed to solve these real-world stage problems in a single compact analog unit.

Instead of simply buffering the pickup, it prepares a cleaner, more natural and easier-to-control signal before it reaches the rest of your audio system.

Complete stage control in one compact unit

Modern upright bass players often need much more than a simple preamp.

PiezoZoid combines the essential stage functions normally handled by several separate devices into one compact analog unit.

It includes:

• 10 MΩ high-impedance input
• Three-band analog EQ voiced specifically for upright bass
• Balanced XLR DI output
• Send / Return effects loop
• Phase reverse
• Ground Lift
• Rechargeable battery with USB-C charging

The low-impedance outputs allow direct connection to:

• Bass amplifiers
• Pedalboards
• Mixers
• Audio interfaces
• Powered speakers

For many players, PiezoZoid becomes the central hub of the entire upright bass rig.

More control. Less gear.

PiezoZoid reduces the number of separate boxes required on stage while giving the player greater control over the pickup signal before it reaches the amplifier or PA system.
