The Master Effects Manta Ray 2-Band Bass Preamp is a 2-band EQ bass preamp from boutique manufacturer Master Effects, delivering bass and treble frequency shaping alongside clean preamp gain for bass guitar signal management. 2-band bass preamp format for fundamental tone shaping without the complexity of more advanced multi-band EQ designs.
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.
