2-Channel Bass Preamp Pedal
DualPre is a 2-channel bass preamp pedal that features two channels each will full independent EQ. So, you can use two different basses like an electric bass and an upright bass, or a bass with stereo/dual outputs. Also, you can use one channel for your bass and the other channel for a keyboard or any instrument with a pickup.
2-Channel Direct Box For Recording & Live
Two XLR DI outputs connect the preamp signal to pro/home recording studio interface or live gig mixer. These outputs can be assigned to DUAL mode with each preamp channel having its own dedicated DI output, or to MIXED mode with a single DI output having both preamp channels combined.
Studio Quality Optical Compressor For Pro Sound
The onboard optical compressor has adjustable Threshold, Volume (Gain makeup), Release, and selectable ratios 2:1, 4:1, 8:1. It's located at the end of the signal chain for taming signal peaks after EQ processing and effect pedals, and allows for getting the desired amount of compression.
