Sound and Vision
Back in 1968, guitar amps were intentionally engineered to keep players from experimenting with distorted sounds. We changed all that.

For 40 years we've been proud to contribute to many of the most famous recordings in music history. Our circuits won't ever constrain the color of your sound; rather, they give you the freedom to find it.

Welcome to EHX, plug in and power up!

No brainer here. Nano sized pedal with one volume knob, that's it. The Signal Pad is a passive attenuator that allows you to instantly switch to a different preset volume. It's your own "guitar knob" in a box on the floor, does the same thing when you roll back your own guitar volume. This box will be your other pedals' best friend. Use them in conjunction to experiment and find that sweet spot you desire. The Electro-Harmonix Signal Pad will do more for your sound than you imagine. Can't just have one!

Electro-Harmonix did it again! Introducing another original innovation for the discerning guitarist and musician...

The Big Muff Pi with Tone Wicker is a great distortion/sustainer pedal that will remind you of the classic Pi with new capabilities. The distortion out of this box will expand your tonal palette to new areas. Freedom to flick the switches will result in a sonic assault onto your amp and audience.

Go to your local music store and try one out, you will be going home with a piece of Pi that will make your ears smile with delight.

YouTuber Ketil Strand nails JS Bach's Toccata and Fugue in D minor -- Ketil notes: "I'm using the Micro POG. It's on all the time on the guitar track to fatten up the sound. It's mixed together with the Axon guitar synth organ sound."

YouTuber ToastmachineIdiot reveals, for the very first time, the dark secret of our success. Obey the master. And clean up your room!

For the EHX history buffs, this was recorded back in the mid-70's and was distributed via inserts in magazines such as Guitar Player. It features Jerry Friedman on guitar (Jerry is a studio session legend, and played for Paul Simon, Gloria Gaynor, Bonnie Raitt, Ray Charles, Richie Havens, The Temptations, etc.), Roberto Mighty on vocals (Roberto was a tester/demonstrator for EHX, and now runs his own A/V production company in Boston, Celestial Media), and Mike Matthews twisting the knobs.

Sean (aka ToastmachineIdiot) was nice enough to record his flexidisc -- so now, for your listening pleasure (and please pardon the scratches): Mike notes: "One side had a great demo of the Frequency Analyzer and the other the Bad Stone, which was the first phase shifter to have feedback which was accidntally discovered as an oscillation that we liked and so harnessed."
