Back in the 1970s, EHX occupied two floors on West 23rd Street in NYC (the fifth and sixth) in an area of Manhattan known as Chelsea. Today Chelsea is home to numerous art galleries, but way back when it was the home of Mike Matthews and his crew who were cranking out Big Muffs, LPB-1s and this black & white catalog!

Guitar effects guru, Bill Ruppert, pushes the envelope (hard) of what is possible to achieve with “just” a guitar and a handful of EHX effects pedals. In this latest edition of Effectology Bill re-creates the synthesizers from the Pink Floyd classic “Shine On You Crazy Diamond.” Check it out. This really is one of those things you have to see and hear to believe!

Please note: Bill will be in the EHX Forums to discuss his sounds, settings, and process. We hope you join us there.

So how did YOU learn to love music? Come tell your story over in the EHX Forums. We got to thinking about this question thanks to the following two YouTube videos. The first is of Jimmy Maguire with his son Noah -- we discovered this video because Jimmy is playing through an LPB-1:
The second video is of YouTuber sitonka's daughter Miah Rose laying down loops on her dad's 2880:

In honor of Earth Day, we jump back to Earth Day 1980 to tell the story of the Electro-Harmonix wind-powered umbrella truck:

Shortly following the oil crisis of the late 1970s, EHX founder Mike Matthews wanted to draw attention to the increasing need for alternative energy. As a result, he managed to tap into what you might now call one of the world's first sources of alternative alternative energy.

Here's how it worked: the truck (pictured above and below) drove around the streets of New York City. The resulting wind was enough to spin an umbrella-rigged turbine. The turbine then generated electricity to power a sound room in the truck's bed.

The inside of the truck was actually a small demo space where guitar players could try out the latest Electro-Harmonix gear (that's Mike in the white shirt). The truck drove around the city, randomly picked people up, let them play, and dropped them off. The electricity for the demo space was provided by the wind-powered generator, and the wind was provided by (damn you, First Law of Thermodynamics!) a colossal diesel engine.

The truck was designed by early Electro-Harmonix engineer Bob Myer, who also helped design one of the company's first products, the LPB-1. The picture above shows the truck mid-construction at Bob's home.

Update: Bob just emailed to tell us: "For our Earth Day I resurected the Electro-Harmonix wind power generator. It still works. I mounted it on a trailer and added lights and a meter to show the power being generated. I can tow it with my pick up to demonstrate." (picture below!)

A short excerpt from the documentary film "Fuzz: The Sound That Revolutionized The World" in which Electro-Harmonix founder Mike Matthews tells the story of EHX's first product, the LPB-1.

Mike also reveals the origins of "Muff," which we take care to use very sparingly: Bass Big Muff Pi, Big Muff Pi, Big Muff Pi (Russian), Double Muff, English Muff'n, Little Big Muff Pi, Metal Muff, Micro Metal Muff, Muff Overdrive, and Pocket Metal Muff (all featured in our Distortion, Fuzz, Overdrive category).

The clip also features Chris Ross (Wolfmother) and ends with J Mascis (Dinosaur Jr.) showing off his unbelievable Big Muff Pi collection.
