Independent shopping perspective
The Korena take
Built for acoustic instruments with a range of pickup systems, the PZ-Deluxe combines preamp control, DI output and stage routing in one compact pedal. PZB mode provides a 10-megohm input for piezo transducers, while the EQ, resonance filter and polarity switch give you practical ways to address feedback and shape the signal. Send the guitar-level output to your stage amp and the balanced output to the PA, then mute for quiet tuning or bring in the adjustable boost when a part needs more level.
Strong match
Who this is for
- Acoustic guitar, upright bass, mandolin or violin rigs using different pickup or transducer systems.
- Stage setups that need separate feeds to a guitar amplifier and the PA.
- Quiet on-stage tuning and an adjustable level lift for solos.
