Rattlesnake Audio Probe

Are you having a hard time finding out what component is failing or broken in your pedal project? This is where an audio test probe can be extremely valuable and easy to isolate a problem.

The Rattlesnake Audio Probe is a great tool for you DIY effect builders and modders out there. It allows you to probe the circuit, establishing breakpoints that let you know what the circuit is doing audibly. Following breakpoints is a great way to identify bad components or where their circuit is failing.

You connect a cable from the amp's input to the 1/4" jack on the probe. Connect a cable from a guitar or signal generating device (could be a looper or instrument) into the pedal's input. Insert the black (ground) probe somewhere in the circuit's ground (usually a screw hole on the enclosure chassis), then touch the red probe to the component. I typically tend to start at the input, which should give you a clean, unaffected tone, then work down the trace until you identify a problem.

The probe is not meant for high voltage devices. The Audio Probe is designed to test simple 9V circuits like pedals.

Please check out the video below. This video shows how I used the Rattlesnake Audio Probe to diagnose a faulty IC in an old MXR Distortion+. The distortion was very "farty," clearly, something was wrong in the circuit. But where? By navigating the circuit, I was able to isolate at the IC. Once I determined that was the problem, I replaced the IC, and the MXR Distortion+ was back to sounding great!

Answer
Absolutely not. This is for low voltage applications. This is ideal for pedals, etc. But not for amps.
Answer
No. This is a passive circuit that will flow signal to an amp. Basically short circuiting the signal and bypassing to an audio device. No batteries or power supply required.
Answer
You can plug a guitar, but is awkward to play and probe at the same time. We would recommend some type of looper that loops a consistent signal into the pedal so you focus on probing.

Aubrey G. - I got the audio probe based off a recommendation from wampler pedal design course and it's fantastic.

I found my first Rattlesnake instrument cable at a small shop in Orange County, Ca while visiting the area. I was impressed with the build quality and look. I opted for the copper weave. When I got home I showed it to another guitar player friend of mine and he immediately ordered a couple of his own. After several months of using it, I decided to order an XLR in copper to match. Ordering was easy on the website and I was informed each step with a confirmation, build, and shipping. When it arrived I was surprised to see an instrument cable as well. Then I saw the hand written "Thank you" note also stating that I won the daily giveaway! Amazing! Thank you for these great cables that I know I can rely on again and again!

I have been so impressed with Hank and the Rattlesnake Cable Company. Not only with the absolutely amazing quality with their products (which are truly really amazing), but with the customer service. You will not find better customer service in the music business, or any other business for that matter. There are cable companies out there that make great cables but I guarantee you won't find a better product than anything RCC makes and you for sure won't find better customer service anywhere. After purchasing a TRS splitter and TRS cable from them I am a customer for life. Any cable I need in the future will FOR SURE be a Rattlesnake. But what truly made me appreciate them was when I enquired about a solution to an odd speaker cable need, instead of giving me an answer that could have easily sold me another Rattlesnake cable Hank gave me the advice to not introduce another cable into the chain and stick with my initial solution. That was what really made me know that not only do they make super solid boutique quality products but they are a company that stands on honesty and hard work and puts the customers needs before their own. Hank, you are a true gentleman and you have earned a customer for life. Thank you sir

I needed a new cable, and Rattlesnake Cables had been recommended to me more than once, so I figured: handmade in Montana, by a small independent company, getting great reviews? Heck yeah! I was not disappointed: a clean, clear signal, coming from a well-made, heavy duty cable, with the coolest wrap idea I’ve seen in a long time! Kudos on the packing too, minimalistic and environmentally friendly while still being high quality (and nice add-ins as well). Bottom line: I’m super glad I took a chance on Rattlesnake Cables, and I think you will be too!
