Detail 01
Independent channel controls
Gain, bass, middle, treble, Crunch/Overdrive, and Normal/Tight settings can be set separately for the two channels.

Independent shopping perspective
Built around the Soldano SLO-100 design, the SLO II is a two-channel tube preamp module with separate gain and three-band EQ control on each side. Each channel also has its own Crunch/Overdrive and Normal/Tight switches, so one setup can remain open while the other is configured for a tighter low end. Two 12AX7 preamp tubes provide the module’s all-tube design. A three-position PCB cathode-select switch further configures input-tube bass response.
