The Smirmoor Saule is a hand-made overdrive pedal from Smirmoor Pedals, described by the maker as designed to "illuminate your sound". It is a hand-made pedal with a unique circuit based on a ProCo RAT, built for standard or low-tuned guitars, which places it in the same family of gain pedals as distortion pedals and fuzz pedals while carrying the overdrive label1.
What it does
The Saule is an analog overdrive. According to the maker's product page, "the Saule combines warmth and clarity to elevate your tone. Whether you're crafting shimmering clean sounds or rich, textured overdrives"1. In other words, Smirmoor positions it as a gain pedal that can run from light, clean-adjacent boost territory into fuller overdriven textures, rather than a one-sound distortion box.
Because the circuit is based on a ProCo RAT, players familiar with that pedal will recognize the starting point: the RAT is a gain circuit that sits between overdrive and distortion, and the Saule takes that as the basis for its own unique circuit. The maker specifically notes it is designed for standard or low-tuned guitars, which is worth knowing if you play drop tunings or extended-range instruments, where many overdrives are voiced to thin out1.
Key specifications
The Saule draws 30mA. That is modest by modern pedal standards, but it is worth checking against the budget of whatever power supply or daisy chain you plan to run it on1.
Where it sits on a board
As an overdrive, the Saule belongs to the broad family of gain pedals covered on the site's Overdrive Pedals page. Players comparing it against other light-to-medium gain circuits may also find the Boss SD-1 vs Ibanez TS9 Tube Screamer comparison useful background on how classic overdrive voicings differ, though the Saule's RAT-based circuit is a different starting point from either of those1.
