Micro Synthesizer

Analog Guitar Microsynth

From the classic vintage sounds of the great early Moog synthesizer to custom creations, the Microsynth creates fat analog synth sounds heard on classic recordings by some of the finest musicians in the world. Compact ten-slider layout lets the sonically adventurous guitarist dial in a virtually limitless array of analog synthesizer sounds: from percussive stabs to backwards-sounding bowed effects.

1979, a first class U.S. postage stamp costs 15 cents, a loaf of bread 43 cents and a gallon of gas 86 cents. Across the pond, Margaret Thatcher becomes the first woman ever to be elected Prime Minister of the U.K.

Closer to home, another Brit, Sid Vicious, dies of a heroin overdose while on trial for the murder of his girlfriend. Nancy Spungen succumbed to a single stab wound. Her body was found in their room at the Chelsea Hotel, which was actually located up the block from Electro-Harmonix at 222 West 23rd Street in NYC. Meanwhile, Mike Matthews and the boys down at 27 West 23td Street, were busy getting the word out on the revolutionary Micro-Synthesizer with this ad.

Sonic master Bill Ruppert reproduces the legendary Pink Floyd synth textures from “Welcome To The Machine .” Using only his guitar and the perfect blend of EH pedals, Bill re-creates the amazing sound-scapes that made this recording special. Each EH pedal provides its own magic to reveal the complexity and textures of the EMS VC3 synthesizer with stunning accuracy.

Welcome to the tenth installment of EHX Effectology. In this episode Bill demonstrates a sound that reminds him of the keyboard sound in the Led Zepplein song “No Quarter”.
Second example is more of a traditional Fender Rhodes sound with a solo using the guitar into a Voice Box whistle mode.

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!

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.
