Soldano’s Super Lead Overdrive 100 (SLO-100) set the standard for modern high-gain amplification. It all started in 1987, when Seattle- native Mike Soldano built one of the first high-gain amp heads with searing harmonics and the perfect balance of gain, sustain and tight touch response. Soon after Mike moved to Los Angeles and displayed his revolutionary amp at the 1987 NAMM show. It didn’t take long for the industry to take notice. The now legendary SLO-100 had arrived!

The SLO completely changed what players came to expect from amps. They shelved their old amps and replaced them with this foot- switchable 100-watt monster, loaded with player-friendly features. While the amp’s drive channel found it backing up renowned rock guitarists like Mick Mars (Motley Crue), Warren de Martini (Ratt), and Howard Leese (Heart), its clear and tactile clean channel and bluesy crunch also made the SLO the first choice for non-metal stalwarts, such as Mark Knopfler, Eric Clapton, Warren Haynes, Gary Moore and Lou Reed to name a few. Today, the amp’s tone and steadfast reliability remains a go-to for thousands of guitarists around the world.

History of the SLO-100R (Rack)

Like many of Mike Soldano’s creations, the rackmount 100W Super Lead Overdrive was a product driven by the needs of professional touring guitarists. In the fall of 1987, Vivian Campbell (Dio, Whitesnake and Def Leppard), requested Mike to build him a couple of custom amps. Vivian heard the SLO-100 Steve Lukather recently purchased and loved the way it sounded, especially the Overdrive channel.

Vivian was having Bob Bradshaw design a new rack system for
him and wanted it to have the “Soldano” sound, but didn’t want the hassle of hauling around an additional flight case to contain these amps. At his request, Soldano built him two rack-mountable, single- channel SLO-100s.

Vivian didn’t need both of the channels the SLO offered, he was
only interested in the Overdrive channel. It is these two single channel amps that inspired Mike to develop a fully featured SLO-100 rackmount amp version for other guitarists who wanted an all-in- one-case rack system. And with that, the SLO-100R was born.

Unfortunately, by 1990, the popularity of rack-type systems had waned. In total Soldano built only about 200 of the rack amps which have since become the prized possession of the lucky few that own them. The SLO-100R is now back and better than ever!

THE SLO-100 RACK UPGRADES:

Master Level Control - The SLO-100 RACK features a front panel Master Level control that uniformly adjusts the power amp level across both channels.

Depth Switch - Historically, one of the most popular SLO “mods”
is the addition of a DEPTH control to the amplifier’s power section. The SLO-100 RACK includes a three position Depth switch, which in combination of the 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-100 features modern grounding, a DC based filament circuit and circuit separation to avoid crosstalk between the channels resulting in an excellent signal-to-noise ratio without altering the amp’s tone.
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 Soldano’s 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 new Soldano SLO-100R is the perfect combination of iconic design, impeccable craftsmanship and modern performance. Every detail of the original head’s design being accounted for with extreme attention to tone, detail and quality. Mike Soldano created his legendary masterpiece to be the best and most versatile amplifier in the world. Over three decades later, that hasn’t changed one bit.

Warranty - The new Soldano Super Lead Overdrive 100 delivers upon the “SLO’s” legendary reputation in both appearance and performance but with the addition of some wildly popular, player- requested features. The SLO-100 continues to be hand-crafted in the United States using only the highest-grade components and is backed by a limited lifetime warranty.
