The pedals are the brand's presence in the effects world, and they are built to carry the amp's character rather than to be generic gain boxes. Soldano says the SLO Pedal is "crafted using the same cascading gain stages as the flagship amp"5, and Delicious Audio described it as aimed at capturing the sound of Mike Soldano's flagship tube amp56.
The SLO Pedal: the amp's Overdrive channel in a box
The Soldano Super Lead Overdrive arrived in November 2022, with MusicRadar announcing that "the legendary Soldano SLO amp is now available in pedal form"7. Soldano positions it as a high-gain overdrive pedal with the iconic Soldano look inspired by the SLO-100 amplifier5, and Premier Guitar's launch coverage highlighted that look along with its USA assembly4.
The pedal models one channel of the amp. Delicious Audio noted that "the pedal has only one channel voiced after the latter," meaning the amp's Overdrive channel1. Premier Guitar's high-gain buying guide added a practical detail: "It also has a side-mounted deep switch to add low-end punch"6. Gearnews, covering the pedal in its 2022 coverage of new releases, pointed to "the deep bass punch that the Soldano Super Lead Overdrive amp heads are known for"2.
Guitar World's reviewer Trevor Curwen tested it as a drive pedal and concluded8:
"Anyone looking for a responsive pedal for quality higher gain, harmonically rich overdrive and distortion sounds will find it here."
Sweetwater's Don Carr demoed the pedal at launch, describing how it "packs the sound of its legendary SLO-100 tube amp into a pedalboard-ready stompbox"9.
The SLO PLUS: both channels of the amp
In late 2024 Soldano followed up with the SLO PLUS, which adds the amp's Normal channel. Guitar Pedal X reported that "Mike Soldano, in being the completist that he is, decided to deliver a SLO Plus pedal, which included the Normal channel"10. Soldano describes the pedal as capturing the playing experience of both of the SLO-100's channels: the genuine Overdrive high-gain channel and the Normal channel's crunch tones, in a format that also works as a preamp11.
Vintage Guitar's reviewer Charlie Wilkins covered the SLO PLUS in March 2025, describing it as "bringing some of the experience of a legendary amp right to your pedalboard"12. Both pedals are available to order from Soldano's webstore10.
| Pedal | Channels | What it covers |
|---|---|---|
| SLO Pedal | One, voiced after the amp's Overdrive channel1 | High-gain overdrive5 |
| SLO PLUS | Two: Normal crunch and Overdrive11 | Overdrive and distortion, usable as a preamp11 |
Soldano and AMT Electronics
AMT Electronics, a separate pedal maker, sells the S1 preamp pedal with the pitch "Make ANY amp sound like a high Soldano"13. That is a marketing reference, not a partnership: AMT states that the names used in its materials are trademarks of their respective owners, which are in no way associated or affiliated with AMT Electronics14. Soldano's own pedals are made by Soldano Custom Amplification5.
Where the pedals fit
For a player weighing gain options, the SLO Pedal sits in overdrive territory at the high-gain end, with reviewers hearing distortion sounds in it too8, while the SLO PLUS doubles as a preamp pedal with its clean and crunch Normal channel5815. The amp that started it all, the Soldano Super Lead Overdrive 100-watt tube amp, remains the reference point for everything with the Soldano name on it.

Questions
Is the Soldano SLO pedal an overdrive or a distortion?
Soldano calls the SLO Pedal a high-gain overdrive pedal, built with the same cascading gain stages as the SLO-100 amplifier. Reviewers have described it as covering both overdrive and distortion territory, with Guitar World's reviewer pointing to its harmonically rich higher-gain sounds. The SLO PLUS adds a Normal channel with crunch tones alongside the Overdrive channel.

Does the SLO pedal look like a Soldano amp?
