In Effectology 12, pedal wizard Bill Ruppert reproduces the sounds of the Irish Uilleann pipes with a realistic and haunting backdrop. Ethereal Harmonic Drones, giant “Field Drums” and the elegant strings are crafted with the perfect integration of his guitar combined with quality Electro-Harmonix effects.
The “Spectral gate” on the HOG combined with the Big Muff Pi provides a harmonic filter that focused the beautiful string tone.The Cathedral Stereo Reverb preserves the reality with the perfect spatial ambience.
Please note: Bill will be in the EHX Forums to discuss his sounds, settings, and process. We hope you join us there.

Enjoy Deerhoof, live in the studio, covering a song from an obscure 1967 movie soundtrack. The performance is from New, Improved, LIVE, a video series by The Bay Bridged (San Francisco Bay Area independent music blog) and New, Improved Recording (Oakland recording studio).
The video starts with Deerhoof guitarrists John Dieterich (plaid shirt) and Ed Rodriguez (green shirt) playing thier HOG and Micro POG (respetively), followed by a look at the studio. The song itself kicks in at about 2:10.
Ed tells us: "The EHX Micro POG has gotten the 'what pedal are you using?' question more than anything else I have ever owned. It's simple to use with great sound quality. It tracks better than any other pedal I've ever used, the Boss PS-5, Digitech Whammy Pedals, everything."
Ed continues: "John (Dieterich) uses the HOG as well and we were both overwhelmed at the possibilities it opened up. It's rare to find pedals you know will always have a place in your set up. In the video of 'Let's Dance the Jet' John opens the song with the HOG making jet sounds and I come in on the melody using the Micro POG and the Holy Grail Plus. Enjoy!"
Be sure to catch Deerhoof on tour. For photos from the session, see the New, Improved, LIVE Facebook album.

Welcome to the third installment of the EHX Effectology series. Today Bill Ruppert presents "Cello Concerto for Guitar and Effect Pedals" (pedals used: for the 'cello' it's just a HOG and Holiest Grail, and for the backing pads Bill also uses a Black Finger, POG, Stereo Polychorus, and Stereo Memory Man with Hazarai).
I especially liked how Bill used the HOG to pitch-shift his guitar down into the register of a cello. That plus the slow attack makes this one especially fun to try, and quite easy to reproduce.

Welcome to Electro-Harmonix's new "Effectology" series. Over the next several months we're going to play a remarkable collection of EHX-assisted sounds, and explain how they were made.
In the first episode, effect pedal wizard and Chicago studio musician Bill Ruppert transforms his regular electric guitar into a blues harmonica (pedals used: HOG, Micro Synthesizer, Wiggler, Holiest Grail).
Please note: Bill will also be in the EHX Forums to discuss his sounds, settings, and process. We hope you join us there.
The EHX Effectology series was originally inspired by Bill's recreation of the synth intro to The Who's "Won't Get Fooled Again" (see here). Stay tuned, more Effectology episodes coming soon!

Sam Ash recently posted this clip of Dan Miller demonstrating the HOG from inside our NAMM show booth. It's a neat quick show of the range of deep synth sounds you can get from the HOG.

Cheers to Jack Conte for "This Disaster," his latest 'videosong' -- I spotted a HOG, a Big Muff Pi, and a Tube Zipper (and for EHX shirts, check out the merch shop).
btw, Jack's videosong rules are: 1. What you see is what you hear (no lip-syncing for instruments or voice). 2. If you hear it, at some point you see it (no hidden sounds).

This video knocks me out. Studio musician (and EHX Forums contributor) Bill Ruppert used his HOG, with a little help from his Stereo Memory Man with Hazarai, to reproduce one of the most instantly recognizable sounds in Rock & Roll history: the intro to The Who's "Won't Get Fooled Again."
In the video Bill shares his settings and performace notes, and adds: "All done with a regular guitar, a regular pickup, and a regular cable!"

Be sure to catch John Frusciante's comments on the English Muff'n in the April 2009 issue of Vintage Guitar Magazine: "The Electro-Harmonix English Muff'n tube fuzz has some really extreme EQ and a big, thick and meaty sound. I used it on the solo for 'Enough Of Me.' I turn the EQ up, but leave my  guitar tone knobs down and use either the middle or neck pickup so the original source sound is really dark and plain. If you blast the tone controls on the effect, you get a really thick, beautiful sound that reminds me of an exaggerated Eric Clapton tone in cream, where you have this really smooth fuzz."
In addition to the English Muff'n, John has also toured and recorded with the Micro Synthesizer, Big Muff Pi (both USA and Russian), POG, Metal Muff, HOG, Holy Grail, and Deluxe Electric Mistress. That said, I'm sure you fru-heads are still going to email and tell me what I left out.

We've been playing these EHX Strings ever since we first took them home to try them out, back in 2002. We find them to consistently offer rich harmonics with powerful definition, while also lasting longer and staying in tune longer than conventional strings. We use them, we like them, and we think you will too. Available in 9's, 10's, 11's. |
