Frequently Asked Questions
Does my StroboStomp HD require calibration?
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.

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

Peterson Connect does not detect my StroboStomp HD in Linux environment.
Chrome needs access to /dev/hidraw*, so either set "chmod a+rw /dev/hidraw*" or start chrome as root with the --no-sandbox option
*Some Ubuntu based distros do not allow running Chrome as root with the --no-sandbox option enabled. -Running as root without --no-sandbox is not supported. See https://crbug.com/638180. You can however run Chromium as a normal user and invoke that option.
Some users have reprted a fix by adding a new udev rule as follows: KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev", ATTRS{idVendor}=="2368", ATTRS{idProduct}=="*SEE BELOW"
* Some Peterson products operate in two different modes with individual product id's for firmware update operations. Multiple rules may need to be created. Here is the list of Peterson USB product ID's
idProduct =
Stomp Classic = 8002
StroboPLUS HD = 0003
StroboPLUS HD Firmware Mode = 8003
StroboClip HD = 8004
StroboStomp HD = 8005
StroboPLUS HDC = 0006
StroboPLUS HDC Firmware Mode = 8006
If there is trouble connecting or reconnecting as a product is switching modes, ex: StroboPLUS HDC product id 0006 to StroboPLUS HDC Firmware Mode 8006 run the command:
"sudo chmod a+rw /dev/hidraw*"
This command will solve any "waiting on user input" or if the update button in Peterson Connect is unresponsive. The command may need to be executed more than once.

What is a Guided Tuning?
The result is an accurately tuned guitar tuned to the required alternative tuning.
Using Peterson Guided Tuning, it is not only possible to try out new tunings without any other reference whatsoever, it is also entirely possible for someone with no previous musical experience at all to consistently, accurately and easily tune a 5, 6, 7, 8 or 9-string guitar to any tuning.

Some 'velcro' does not stick well to the bottom of my StroboStomp HD
To help, the rubber pad can be cleaned thoroughly with isopropyl alcohol and let dry. Then, use a heavy-duty (or industrial) hook and loop type fastener. We recommend 3M Dual Lock tape. Let the tape cure at least 4 hours before trying to pull it for maximum adhesion.
We offer a hook and loop pad which is meant to replace the rubber pad. To install the hook and loop pad:
- Remove the rubber pad from the bottom of your tuner
- Remove the paper backing from the hook and loop pad
- Align and press the hook and loop pad into place on the tuner
Early models of the StroboStomp HD include the serial number sticker applied to the rubber pad. If this is the case with your tuner, the serial number sticker may be removed and placed into the window of the hook and loop pad, or the original rubber pad with the serial number sticker may be stored in a safe location should you need the serial number in the future.

I often tune my acoustic instrument in a loud environment. What's available to help with that?
A Peterson TP-3 clip-on tuning pickup is a very versatile device with a 1/4" connector that can be clipped onto any portion of the instrument that vibrates, such as the headstock of a guitar or the bell or lead pipe of a horn.
A Peterson Pitch Grabber Mobile Tuning Clip utilizes a 1/8" connector for use in mobile phones or tablets with software tuners.
For instruments with a flat resonating surface, you can use a suction cup tuning pickup to reduce ambient noise interference.
