Frequently Asked Questions
What power supplies can be used with my Peterson Pedal Tuner? ( StroboStomp 1 & 2, Stomp Classic & StroboStomp HD )
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 high definition. They require very precise 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.

How do I install my StroboStomp HD screen protector?
To apply your StroboStomp HD screen protector:
- DRY FIT: Without removing the backing to the screen protector, lay it over the StroboStomp HD display to dry fit the protector. The protector should sit precisely over the existing display opening.
- CLEAN: Use the wet alcohol pad (green package) to clean the StroboStomp HD screen paying special attention to the corners of the display.
- POLISH: Use the cheesecloth (orange colored) to LIGHTLY polish the display and remove any leftover streaks from the wet pad.
- REMOVE: Making sure the StroboStomp HD display is clean and lint-free, remove the backing from the screen protector and take precaution to not touch the exposed side.
- POSITION: Position the screen protector starting in one corner of the StroboStomp HD display and SLOWLY lay it on to the screen. You can lightly adjust any positioning at this time to make sure it is centered on the display. If you see large air pockets, lift the protector up and re-lay it.
- PRESS: Lightly press the protector starting from the corner you began with working towards the opposite end to remove any air pockets out from under the screen.
TIPS:
- If you do not lay it correctly the first time, it can be lifted and re-applied a few times before the undercoating starts to break down. Use a toothpick, fingernail, or credit card edge to get under one corner of the protector to slowly lift it up.
- Any lint that is trapped under the protector can be removed by washing the protector in a mild dish detergent. Make sure it is completely dry before trying to re-apply.
- A credit card edge - wrapped with the provided polishing cloth - can be used to help work out any air bubbles.
- Make sure your installation environment is not excessively dusty to avoid issues.

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

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.
As a last resort, the rubber bottom can be removed. Store it in the box with the serial label for future reference.

I often tune my acoustic instrument in a loud environment. What's available to help with that?
For instruments with a flat resonating surface, you can use a suction cup tuning pickup to reduce ambient noise interference.
A Peterson TP-3 clip-on tuning pickup is a very versatile device 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.
