Shared three-band EQ
Both channel settings use the same bass, mid, and treble controls.

Independent shopping perspective
Mike Soldano designed this SLO preamp module to bring the SLO-100’s thick sound, creamy gain, and sustained lead character into a dual-channel format. The two similarly voiced 12AX7-powered channels can be set at different gain and volume levels, making it useful for moving from tight crunch to a more prominent lead voice. Both channels use one three-band EQ, while the Cathode Select switch offers three input-tube bass-response configurations that alter feel and tightness. The factory configuration is position 3.
