Keytar, Serge, Sonica @ 30 June 2015, Comments Off on Frank Eventoff Sonica

sonica“Travel back in time with this vintage Sonica. Yes, it is an unusual instrument. Around 1979-1980, only 650 were built. It’s really a synthesizer that looks like a mini-guitar/sitar. The tone is something like a theremin. To hear the actual tone, there are various Youtube videos of folks playing one. This one is numbered 410. It’s only about 20” long. It has its own little speaker and runs on a single nine volt battery. It has two octaves. All the notes on the headstock are major, but there is a half-step button on the body. The key is adjusted by a key knob. Yes, it is an odd duck! It is quite well made with a wood body (carved from Red Alder) and brass front, back and rear head stock plates (coated with baked enamel). The “fretboard” is also side with brass. This one is in good condition except for tears on the interior speaker grill cloth. The brass plating is tarnished, but I didn’t dare scrub it with Brasso. It comes with the original (cute as the dickens) black chip board case with two piece of case candy. The mini six-page instructional booklet and warranty and the Sound Instruments warranty card (with the original 15 cent USPS “1980 Winter Olympics” speed skating stamp). It has an odd “in-tune” function: “Play the middle diamond… on the keyboard and turn the Key knob until the note sounds in tune with the music you’re listening to.” It also has an 1/8″ output jack for a regular amplifier. Ol’ Eric Clapton had one of these that was sold at his 2011 Bonhams auction for over $3,400. (Check it out online.) The inventor of the Sonica, Frank Eventoff, previously invented the popular Magical Musical Thing, and now runs Sensitronics, which is still on the cutting edge of experimental electronic musical instrument technology. I know I listed it in vintage guitars too (besides synthesizers) because it looks like a guitar, but it has no strings. It is all controlled by touching the notes on the headstock. For USA orders, shipping is free. It will be shipped in brand new cardboard 46” by 19” by 7” guitar box (which will be shortened to ship this) with plenty of new 1/2″ bubble wrap.” Click here to visit listing on eBay

sonica“Some scratches, mostly working needs a skilled solder on fret board from the 14th to the 10th fret working fine. someone showed me what needed to be done, I just don’t know anyone who can solder that well. It was given to me by my father, my kids have played with it a couple of times so there are small scratches here and there. speaker cloth is torn but the speaker works fine and is all original. everything else works fine. all knobs and synthesizer effects work fine just not two thirds fret board.” Click here to visit listing on eBay

“Up for auction we have this Rare Frank Eventoff Sonica Synthesizer #507 out of 650. It does have a few scratches and the brass plating is a little worn, however I have not tried to clean this up and it may very well just need cleaning. It is in working order but I could not get any sound out of 2 of the round buttons on the base.The case is also a little worn but fully functional. It’s all original. Offered from the estate of the late Richard Waters, inventor of the Waterphone as well as other musical instruments and Multi Media Artist.

The Sonica is indeed a Serge oscillator. The body is made of carved mahogany. There is a plug/jack included as well. If you are a collector of musical instruments this is a great find! Bid to win!” Click here to visit listing on eBay

“I am the original owner of this very rare Frank Eventoff Sonica. I bought it straight from him back in either ’78 or ’79 while I was working at Hollywood Sound, and he happened to drop by the studio. I have played it some, as you can see some wear at the bottom of the instrument. Everything is in excellent condition, and plays as well as it did then. It is hand carved mahogany, with brass plates.

Comes with original case and original instructions.

This is a LOW number of only 650 made…it is #092.” Click here to visit listing on eBay

This is my super rare 1/600 Sonica Limited Edition Synthesizer made by Frank Eventoff in Los Angeles in the 70’s. In excellent condition, although the thin foam membrane covering the speaker has disintegrated and can and should be replaced. There are two small dark streaks on the brass near the half-step button that are minor original blemishes. The case is included as well as the original paperwork. This is a fun little unit for jamming on and is very easy to play. The output jack is a strange 1/8” that I haven’t found the exact right plug to fit it. I have just played the internal speaker and recorded to mic. Some info from the documentation:
“The Sonica is a portable self contained synthesizer designed to simplify the playing of music… an electronic sensor that converts the pressure of your touch into creative musical tones and expressions… carved from Red Alder, a domestic hardwood. several coats of lacquer. Finished by hand. The face and trim are solid brass protected with baked enamel finish. ” Serial Number 592, one of last ones made!” Auction ended. Click here to browse on eBay.

sonica_1 “Up for auction is the extremely rare Sonica, built by Frank Eventoff. Only 650 of these were ever produced, making it a highly collectible electronic device. Very few are now known to exist, even fewer in working condition.

In 1979, the first Sonicas were produced, a collaboration with Larry Heller. There were 650 built, but very few are seen nowadays. Serge Tcherepnin of Serge synthesizers (producer of high-end modular synths!) did the oscillator design, and the oscillator inside the Sonica is indeed a Serge oscillator. The neck is incredibly comfortable, and easily fits into the hand, facilitating the sliding action used for playing the Sonica. Creator Frank Eventoff’s neighbor in Silverlake was a modelmaker and carved the bodies – they produced them in runs of 24 at a time. The body is made from finely hand-carved mahogany. Donna Summer bought one of the runs of 24 and created a Sonica Orchestra.

The sound of the Sonica can best be described as somewhere between a sitar and violin. When run through a simple delay, an amazing array of soundscapes are derived. The front panel features a Key/Pitch Knob, and an On/Off Volume Knob. It also features three buttons. “Slider,” which is a tremolo type effect, “Tone,” which is actually a tonal boost, and “Half-Step,” which raises the note an octave. It features a built-in speaker, with an 1/8 inch output to connect to an amplifier or recording device. It runs on one 9-volt battery which is installed by accessing a plate on the backside of the device. The Sonica really shines when sent through a tube amplifier, producing a crystalline sound unlike anything I’ve heard before.

This unit for auction is in very good shape cosmetically and works as it should. Because of the age of the electronics, it’s being sold as-is with all sales final. Will ship this item worldwide. Free shipping is only for the US. International to pay actual postage cost.

Very conservatively, there are probably a couple hundred of these in working condition today, most of which have been abused in one way or another. This one is in great cosmetic shape and was purchased NOS from an original investor. Since being purchased, it has been played briefly.

This device includes the original carrying case, original owners manual, warranty registration card (unused), and a business card from Frank Eventoff at Sound Instruments. ” Auction ended. Click here to browse on eBay. sonica_2sonica_3
