It’s Pi Time!
Don’t forget that March 14 is National Pi Day, a geeky celebration of our favorite irrational number, which is approximately 3.14159265. In case you didn’t know, in audio circuit design we use pi all the time to calculate frequency cut-off points for many applications including filters, tone controls, noise reduction, and pretty much anything else that impacts which frequencies in a circuit are affected as part of the effect, perhaps one of the most fundamental aspects of audio circuit design. Most places where you see a capacitor in an audio circuit, a calculation involving pi was used to select its size. Pi Day – we’re all in! Of course, here in Dallas we often use 3.1416 for pi in our calculations, since things are a little bigger here in Texas...
Naturally, Pi Day is a great excuse to begin designing your custom GT rack effects solution around the best-known fuzz effect ever, available as the GT Pi module. We offer many of the known EHX Big Muff Pi variants and derivatives, along with the ability to design your own Pi by choosing custom components and features.
You can find all the details about our Pi module, including the recently-released Fire Pi, at Pi. If you can’t find the type of Pi you’re looking for, just let us know and we’ll likely be able to offer a custom configuration to meet your needs.
