Analog preamp and tone control system designed specifically for cello piezo pickups

Why cello piezo pickups need a dedicated preamp

Cello piezo pickups require proper impedance matching and carefully controlled frequency response to sound natural and balanced.

When connected directly to mixers, interfaces or standard instrument inputs, the sound often becomes harsh, thin or unstable in the low frequencies.

PiezoZoid for Cello is designed specifically to preserve the warmth, dynamics and bow response of the cello while improving control and compatibility with modern stage and studio equipment.

Analog tone shaping for cello

The analog EQ section is optimized for the cello frequency range and allows flexible correction of different pickups, instruments and amplification systems.

Harsh upper mids, excessive piezo sharpness and uncontrolled low-frequency resonance can be adjusted without destroying articulation or natural bow response.

This helps the cello sit more naturally in live and recording environments.

Compact standalone cello setup

PiezoZoid is designed to function as a compact all-in-one cello front-end.

The stable low-impedance output allows direct connection to:

• amplifiers
• pedalboards
• mixers
• audio interfaces
• powered speakers

In many situations, PiezoZoid alone is enough to prepare the cello signal for stage or studio use without additional external preamps.

PiezoZoid DI version

The DI version expands the system into a complete compact stage solution for cello players.

Additional features include:

• Balanced XLR DI output
• Send / Return effects loop
• Direct connection to mixers and PA systems
• Compact pedalboard-style workflow

This allows PiezoZoid DI to function as the central control unit for a complete electric cello setup.
