The Rowin S-Fuzz, model LEF-325, is a compact fuzz pedal from Rowin. RockBoard's PedalPedia describes it as delivering "a smooth, vintage fuzz sound"1, which places it on the softer, rounder end of the fuzz spectrum rather than the aggressive, gated end. It comes in a metal shell that Rowin calls "very small and exquisite"2, making it a candidate for players who want fuzz on the board without giving up much space.
A smooth vintage fuzz in a mini pedal
Rowin's own description of the S-Fuzz is short and to the point: "A smooth, vintage fuzz sound"2. For a player, that points toward the warmer, sustaining character associated with early fuzz designs rather than modern high-gain clipping. The pedal sits in Rowin's mini format, a metal shell at roughly 95 mm deep and 45 mm wide2, so it occupies about the same board space as a standard mini pedal.
The S-Fuzz is one of several fuzz pedals in Rowin's range. Players comparing options can also look at the Rowin Fuzz, the Rowin G-FUZZ, and the Rowin LEF-606 Fuzz, each with its own voicing and feature set.
Power and connections
The S-Fuzz runs on 9V DC with a center-negative plug2, the arrangement shared by most guitar pedals on the market, so it works with typical multi-output pedalboard supplies. Its current draw is only 3 mA1, which is low enough that it places almost no demand on a shared supply.
Connections are simple:
The pedal is true bypass2, so with the effect switched off the guitar signal passes through without active circuitry in the path. For players who chain many pedals, that keeps the bypassed tone close to a straight cable, though long cable runs can still benefit from a separate buffer.
The 9V DC center-negative requirement means the S-Fuzz needs a proper pedal power supply. Nothing in the listed specifications indicates a battery option, unlike some larger fuzz pedals such as the Wilson Effects Fuzz MKIII, which runs on a 9VDC 2.1mm center-negative supply or a 9V battery3.
How it compares with other fuzz pedals
The S-Fuzz's smooth vintage description and mini format distinguish it from other fuzzes on the market. The Tomsline Engineering S-FUZZ Silicon Fuzz, for example, is described as a "classic silicon fuzz" with true bypass and the same 9V DC center-negative power requirement4. Silicon clipping is associated with a brighter, more aggressive fuzz character than germanium, so players chasing a smoother vintage feel may find the Rowin's description more aligned with their taste.
Other makers take different approaches to the same effect. The R Weaver FX Silicon Face of Spades Fuzz uses true bypass to switch the fuzz effect in and out5, while the FuzzHugger Euphonia Bass Fuzz, aimed at bass players, accepts 9V to 18V DC for extra headroom6. The Rowin S-Fuzz's 3 mA draw and mini enclosure put it on the practical, board-friendly end of that spectrum.

Questions
Is the Rowin S-Fuzz true bypass?
Yes. Rowin lists the S-Fuzz (model LEF-325) as true bypass, so when the pedal is switched off the signal passes through without active circuitry in the path. That suits players who want to keep their clean tone untouched when the fuzz is disengaged.
What power supply does the Rowin S-Fuzz need?
It runs on 9V DC with a center-negative plug, the standard arrangement for most guitar pedals, and draws only 3 mA. That low current draw means it is easy to power alongside other pedals from a typical multi-output supply.
What is the difference between the Rowin S-Fuzz and G-Fuzz?
The S-Fuzz is Rowin's smooth, vintage-flavored fuzz in a mini enclosure, listed at $58.00. The G-Fuzz is a separate Rowin fuzz pedal with its own voicing and its own page covering its specifications and character.
How big is the Rowin S-Fuzz?
Rowin lists the S-Fuzz at 95 mm deep by 45 mm wide by 53 mm high, with a weight of 278 g including its box. That footprint is in line with other mini-format pedals, so it fits into tight spots on a pedalboard.
