Preamp For 1 Bass, 2 Basses, 1 Bass + Other
2-channel bass preamp/DI pedal with full independent EQ strips on each channel. So, you can dial in two different EQ settings for your bass, and select either EQ with the onboard channel footswitch. Also, you can use two basses, or a bass with stereo/dual outputs, or a bass and a keyboard or any instrument with a pickup. Set the EQ for each bass/instrument, and select it with the footswitch.
2 Independent Channel DI Outputs
Each preamp channel has its own dedicated XLR DI output for connecting to pro/home recording studio interface or live gig mixer. The DI outputs can be assigned to DUAL mode, or to MIXED mode with a single DI output having both preamp channels combined.
Studio Quality Optical Compressor
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.
