the plug. If the plug should still fail to fit, contact
your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized
plug.
11. Power-Cord Protection
– Power-supply cords should be routed so that

only as recommended by the manufacturer.
Clean by wiping with a cloth slightly damp with
water. Avoid getting water inside the amplifier.

14. Non-use Periods – The power cord of the

biasing
17. Servicing – The user should not attempt any
service to the amplifier beyond that described in
the operating instructions.
All other servicing should be referred to qualified
service personnel.
18. Ventilation – Slots and openings in the

product before a lightning storm, or when it is
left unattended and unused for long periods of
time, unplug it from the wall outlet. This will
prevent damage to the product due to lightning
and powerline surges.
22. Replacement Parts – When replacement
parts are required, be sure the service technician
has used replacement parts specified by the
manufacturer or have the same characteristics as
the original part. Unauthorized substitutions may
result in fire, electric shock, or other hazards.
23. Safety Check – Upon completion of any
service or repairs to this product, ask the service
technician to perform safety checks to determine
that the product is in proper operating condition.
24. FUSES – Always use the correct rating and
type of fuse as indicated on the rear panel. Note
the proper rating fuse is determined by the AC
line voltage in the country this unit is being
operated.
25. AC SELECT SWITCH: This switch must be set
to match the AC line voltage in the country this
unit is being operated.
To change the setting, loosen (do not remove)
the two screws above and below the slide switch.
Temporarily move the protective cover strip and
slide the actuator to match the voltage in your
country. Place the protective cover strip back
over the switch and tighten the two screws.

Thank you for choosing the Soldano SLO-30. We hope you enjoy playing it for decades to come.
This amplifier sings and roars with the same voice of its iconic bigger brother, the SLO-100. It’s a harmonically
rich character that remains at the forefront of modern high-gain electric guitar amplification. But this 30-watt, all-
tube head is optimized to today’s studio and stage applications.
Onboard your amp, you’ll find the same Normal and Overdrive channels - including independent Preamp (gain)
and Master controls - that Soldano fans have 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 LINE OUT, just like the original.
SLO-30 Highlights:
Depth control
Historically, one of the most popular SLO “mods” is the addition of a DEPTH control to the amplifier’s power
section. The Depth control is now standard on the SLO-30. The combination of the Depth and Presence controls
provides a powerful EQ section that goes well beyond a typical tone stack, enhancing the tonal possibilities of
the amp’s sonic character.
Improved Noise Floor
The new SLO-30 features modern grounding, a DC based filament voltage supply and circuit separation to avoid
crosstalk between the channels resulting in an excellent signal-to-noise ratio without altering the amp’s pure
amp.
Versatile & Transparent effects loop
The newly designed ultra-transparent tube-buffered effects loop handles anything from vintage pedals to high-
powered rack units.
Front panel channel switching
Players familiar with the original SLOs will be elated at our inclusion of an onboard channel-select toggle switch.
Perfect for applications such as studios, where you don’t want to rely on a footswitch.
The SLO-30 is proudly hand-crafted in the United States using only the highest-grade components and is backed
by a lifetime warranty. Thank you again for choosing the SLO-30 - we hope you enjoy playing it for decades to
come…
