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.

What Jason S. Said...


Testimonial:

I have purchased personally from Rattlesnake twice and have referred at least three people to purchase as well. I can tell you that the customer service for every single person hasn't been above and beyond what is called for. The quality of rattlesnake cables is on par with anything else out there regardless of price. I have spent a whole lot more on so-called boutique cables, only to have them fail from their construction methods. I used tons of cables and testing and playing both and have had not one inkling of an issue with any single Rattlesnake product.

Thoughts about our Service:

Every step of the way Rattlesnake cables has been in communication, from the time you place your order till the day it ships you have nothing but stellar communication. Not only that you get a lot of personalization along with that stellar customer service. Unless something goes Topsy turvy in the world I doubt I'll be purchasing from other cable companies anytime in the foreseeable future.

What was purchased:

I have two 10-ft "L"cables, one 15 ft straight cable, and many pedalboard patch cables. I also got one of Rattlesnakes test probe boxes for building pedals. I have also bought some effects pedals and other things recommended by Rattlesnake all with the same quality of service.

I just received my second order from Rattlesnake Cable Company. The pair of cables I received in my first order were so impressive, I placed a second order for some cables to give as gifts. They were equally impressive. The service was VERY fast. Mr. Donavan contacted me directly with my first order to make sure of exactly what I wanted; it was sort of a custom order. His packaging is FIRST CLASS, and these cables are MADE IN THE U.S.A. Also, for Tele players, he has a special right angle plug available that works in ALL Telecaster inset jacks; the plug is a little bit longer. It works PERFECTLY. Every guitar, bass, keyboard player should have at least one PREMIUM cable in their gig bag. And once you see these, you will want to have more than one.
