Backstage, under the red glow of a spinning Peterson strobe wheel, Eddie Van Halen relied on Peterson tuners as he shaped a sound that would influence generations of guitarists. The StroboStomp EVH brings that connection forward in a pedal tuner inspired by one of rock's most influential innovators.

At the core of StroboStomp EVH is Peterson's renowned ±0.1 cent tuning accuracy, displayed on a large, high-definition LCD strobe display with a variable-color LED backlight. The distinctive red glow pays tribute to Peterson's tuning heritage, while the versatile output options let you choose between 100% Pop-less True Bypass and Pure Buffered Output to suit your signal chain.

StroboStomp EVH includes more than 150 Sweetened and Guided Tunings for a wide range of instruments, along with 13 exclusive EVH Sweeteners derived from Eddie Van Halen's 1978 landmark album. These specialized tunings give players a way to explore the tuning nuances behind his recordings and bring those details into their own playing.

Combining Peterson's proven tuning technology with a distinctive EVH-inspired design, StroboStomp EVH puts a piece of rock history on your pedalboard.

Does my StroboStomp EVH require calibration?

Generally, your StroboStomp EVH will not require calibration and should remain perfectly accurate if it has not been damaged.

Unlike more modern Peterson strobes, legacy models such as the Peterson 400, 420, 450 and 700 do require occasional calibration.

If you require service, please open a support ticket and return the tuner for repair.

Why did two ‘charges’ appear on my credit card when I made a purchase on the Peterson website?

If your card shows two transactions, the first was an authorization, which may have been rejected because address, zip code or security did not match. This failed authorization will usually disappear within 24 hours.

The second charge is an authorization and approval which resulted in the order processing successfully.

What power supplies can be used with my Peterson Pedal Tuner? ( StroboStomp 1 & 2, Stomp Classic & StroboStomp HD/LE/Mini )

9VDC - Regulated - Center negative - At least 85mA

Partial list of regulated power supplies:

  • Voodoo Lab Pedal Power 2 (Eight isolated 9VDC 100mA regulated outputs)
  • Dunlop DCB-10 DC Brick (10 outputs)
  • Visual Sound 1-Spot (9V fully regulated output)
  • Carl Martin Big John 9v Power Supply (Seven 9VDC outputs 600mA total)
  • Sanyo Pedal Juice
  • T-Rex Fuel Tank
  • Godlyke PA9 Power All (9V 800mA regulated output)
  • Boss PSA120 adapter (9V 200mA regulated)
DO NOT use the Boss ACA120 Unregulated power supply! Boss ACA, Danelectro DA1, RadioShack, etc., do not have a voltage regulator and are not suitable.

As always with any pedal, be careful - check voltage ( 9V regulated ) & polarity (positive barrel-negative inner sleeve) first and don't overload the power supply's ampere rating by daisy chaining too many pedals from a single supply.

How do I read a strobe display?

Basically, the strobe image appears to travel to the left if your instrument is flat of the desired pitch and to the right if it is sharp. On earlier models such as the StroboStomp 1, StroboStomp 2, VS-1, VS-II and V-SAM, the strobe image travels upward if your instrument is sharp and downward if your instrument is flat of the desired pitch.

Adjust your instrument until the pattern is as close to still as possible. Strobe displays are 'real-time' and extremely precise. They require very fine tuning adjustments to stop the display because the frequency/pitch of any instrument is never totally stable.

You'll quickly learn to read the display, make the most precise adjustments and appreciate the high resolution that only a Peterson provides.

Help others find this information sooner.

Is the accuracy the same for all Peterson tuners?

Yes, the accuracy is within 0.1 cents (1/1000 of one semitone) as with all Peterson Strobe Tuners. An important thing to note is that Peterson Strobe Tuners have ultra high definition displays, so not only are they highly accurate in detecting a note but they have the ability to display that accuracy. Other products claim accuracy but do not have the high definition screen to display the level of accuracy in which they claim. If you cannot see the accuracy, it is of little value. Only Peterson provides High Definition Strobe Tuning.
