Ortega MagusPRO/B

Ortega · pedal

The Ortega MagusPRO/B is a piezo bass preamp system built for acoustic bass guitars, combining onboard EQ shaping with a built-in tuner so players can adjust tone and check tuning without a separate pedal. Ortega, primarily known for acoustic and classical guitars, designed this system specifically to address the common weak points of piezo pickups on acoustic bass, namely a thin or quacky low-frequency response that needs active EQ correction to sound full and natural through a PA or amp. The integrated tuner adds practical convenience for acoustic bass players performing live without a dedicated pedalboard.

What stands out

  • “In a chain it functions as the foundational preamp stage, typically built into or mounted on the instrument itself , feeding a DI or amp input directly”
