There’s honestly nothing worse than the feeling of going to jam, and something isn’t working correctly in your chain. It’s a mix of emotions, from sad to angry to just generally a “What the heck?” moment. The next process involved is troubleshooting or searching on the internet for the answer. First and foremost we suggest contacting the manufacturer of the pedal for help. This cuts to the chase by going direct to the source, especially in terms of warranty and beginning the process for repairs (if necessary).This is just a helpful guide of sorts to narrow down areas to troubleshoot on your own prior to moving forward. These are common ways to troubleshoot that apply to nearly every pedal out there.
The first thing to try when anything is acting wacky with a pedal is to isolate it for testing. This removes any other variables and focuses on the cleanest and simplest signal path to troubleshoot. Start with your guitar going out with a confirmed working cable to the input of the pedal, with the pedal having a fresh 9v battery (if applicable, not with minis) and disconnected from your power supply, straight into the amp. If the pedal behaves correctly, then you know the problem was somewhere else in the chain. If the issue is still occurring, document everything you can to better help identify the problem for the tech. If there’s no output, try cutting the footswitch off and on several times, if it comes on occasionally, it could be a bad footswitch. If you turn a knob and the sound seems really odd or has no effect at all, it could be a bad pot. Does the LED cut on? Any small detail will help when you’re going to have it repaired.
Batteries – Some companies ship their pedals with batteries, some do not. Leaving a cable plugged into the input of a pedal will drain the battery, even if it’s not being used. One good idea to practice is if you’re using a power supply to power your pedals, remove the battery to prevent corrosion over time. If you do use a battery, be sure to use a fresh, unused battery
Power – Digital effects especially are more prone to be noisy if you’re not using a dedicated, isolated power source to power the pedal. Daisy-chaining digital effects with analog pedals or other digital pedals will create substantial noise. Isolated power supplies can be a bit expensive, but they’re worth the investment in the long run. If you’re concerned it’s a power issue and you’ve tried it isolated with a battery, then there could be an issue with the cable from the power supply, or with the power jack. Note: Using the wrong power supply can render a pedal useless, and that is not covered under most warranties. Our pedals in particular require a barrel-type (Boss style), center-negative power supply cable. Some pedals have the ability to run anywhere from 9v to up to 18v (and anywhere in between), where some will be rendered useless if run above 9v. Check out this blog for an in-depth detail of which of our pedals can be used at 9v and 18v: http://www.wamplerpedals.com/news/blog/talking-about-gear/power-9v-or-18v
Footswitch popping during activation – If your pedal has recently started an excessively loud pop when you first activate it after moving pedals around on your board, there could be an issue with the impedance the pedal is seeing. For starters, try the first step and isolate it and see if that is taking care of it. If it’s no longer popping, then another pedal in your chain is causing an impedance issue, so try swapping positions on your board could fix it. Bad cables can be the culprit as well.
Crackling Pots – This would signal dirty pots, which can be solved by using an contact cleaner, which is discussed more here: http://www.wamplerpedals.com/news/blog/talking-about-gear/cleaning-the-pots-on-your-pedals
