Peterson StroboStomp Mini

The Peterson StroboStomp Mini is a compact guitar tuner pedal with a precise strobe display, built by Peterson Strobe Tuners, a company with a long history in professional tuning equipment¹. It measures just 94mm x 46mm (H x W), with top-mounted jacks and a small footprint that suits tight pedalboards¹. Peterson lists its accuracy as 0.1 cents, and it carries 80 sweetened tuning presets covering electric guitar, acoustic guitar, bass, baritone guitar and more¹.

It is a smaller version of the popular Peterson StroboStomp HD pedal, trading the HD's larger screen and extra presets for a much smaller housing¹.

What it does: a compact strobe tuner

The StroboStomp Mini is a tuner pedal built around a strobe display, the same approach Peterson has used across its StroboStomp lineup since the early 2000s². A strobe display shows pitch movement in real time as rotating bands, which makes very fine tuning corrections easier to see than a needle or LED display. Peterson's earlier StroboStomp was rated to 1/10th of a cent, which the maker described as 30 times more accurate than LED and needle tuners⁵, and the Mini carries the same 0.1-cent accuracy rating¹.

Note selection is automatic, and the transposition range runs from -6 to +5, so it handles both drop tunings and capo situations¹. The sweetened tunings are the other half of the pitch story: these presets slightly offset individual notes to correct inherent tuning issues with specific instruments. The Mini's sweetened tunings include generic settings for electrics, acoustics, 12-string, and bass, plus the EVH tuning and loads more³. Reviewers of earlier Peterson pedals found the sweetened tunings genuinely effective; MusicRadar's reviewer of the Strobostomp 2 wrote that "it's the sweetened tunings that really work" and that they would not use anything else, save for the Buzz Feiten Tuning System⁶.

Peterson's manual for the Mini suggests using a thumb or finger to pluck the strings instead of a pick when tuning, a tip MusicRadar's reviewer endorsed¹.

The controls and display

The display is an LCD with an LED backlight³. The default background color is orange, and you can choose from nine other background colors if you prefer something else¹. This mirrors the StroboStomp HD, whose multi-color display lets users select preset colors globally or assign them to specific tuning presets².

Sweetener tunings and all the other features are accessible via two pairs of buttons on either side of the pedal³. The footswitch is silent, but it takes a split-second to mute the signal rather than muting instantly¹. Guitar World's reviewer described it plainly: "You depress the switch and then there's a very slight, split-second delay"³. The pedal is well built, with a sturdy and silent switch and a premium metal casing³.

Power and connections: 9V or USB-C

You can power the StroboStomp Mini by a conventional 9V power supply or by a USB-C cable¹. It draws 86mA¹. The jacks are top-mounted, and the connections are an input, an output, a 9V DC input, and a USB-C port¹.

A smaller StroboStomp HD

The Mini is a smaller version of the StroboStomp HD¹, which Peterson unveiled at NAMM 2019⁷. The HD is a larger pedal with 135 sweetened tunings, a bigger multi-color display that doubled the pixel resolution over its predecessor, and a true-bypass mode revamped for a pop-less experience⁸². Premier Guitar's reviewer called the HD "one really robust pedal that feels like a high-tech mini-brick" and accurate to +/- .01 cent, while noting it is "a bit pricier than others in its class"⁸⁹. The HD's custom colors can be configured through Peterson's website app, Peterson Connect, with updates over USB¹⁰.

The Mini keeps the core of that design, the strobe display, the sweetened tunings, and the choice of true or buffered bypass, in a housing about half the width. The bypass choice works the same way: you can choose whether the pedal switches off when your signal is muted, or whether it continues to monitor your tuning while unmuted³. Peterson's earlier StroboStomp offered the same selectable bypass modes, letting you tune while playing or set it for silent tuning with true bypass when the tuner is off⁵.

What reviewers said

MusicRadar's reviewer found the StroboStomp Mini extremely accurate, writing that with the 0.1-cent accuracy claim, "that is easy" to believe after playing around with the pedal¹. Guitar World's reviewer concluded that with its small footprint, top-mounted jacks, accuracy within 0.1 cents, and additional features, it is probably the tuner to beat in its size class³.

Writing at Guitar.com in 2026, Cillian Breathnach described the Peterson StroboStomp HD and Mini line as "pretty much the de facto high-end tuner pedals"¹¹. The main criticisms reviewers raised are the split-second mute delay and the absence of a power output¹³.
