From Soldano:

"Onboard the SLO-30, you’ll find the same Normal and Overdrive channels – including independent Preamp (gain) and Master controls – that we’ve all come to expect from the SLO name. Even the Normal channel’s mini voicing toggle switches are present and accounted for. Turn the amp around, and you’re greeted by a tube-buffered FX loop and variable slave output, just like the original.

Features include:

• 30-watt all-tube head
• Hand wired in the USA
• Legendary high-gain and clean tones that defined modern rock
• Compact design is perfect for today’s studios and stages
• Crystal cleans and harmonically rich crunch tones via the Normal channel’s Bright and Crunch switches
• Thick and incredibly tight driven to distorted tones throughout the Overdrive channel’s range
• Instant switching from the Normal to Overdrive channels via the included footswitch
• Independent Preamp and Master controls
• Global 3-band EQ, Presence, and Depth controls voice the entire amp
• Improved tube-buffered FX loop
• Variable Slave output offers direct recording, use with IRs, combining amps, and more
• Use your 4, 8, or 16-ohm speaker cabinets thanks to the onboard impedance selector
• Preamp Tubes: Five 12AX7
• Power Tubes: Two 5881 / 6L6."
