Monophonic Guitar Synthesizer

Based on the Korg MS-20, the M3 brings the sounds of 70s monophonic synthesizers without the modular complications.

Instead of dual oscillators, the M3 employs 3 digitally controlled oscillators for super fat synth sounds that never go out of tune.

Eleven oscillator combinations cover string sounds, analog bass, bell tones, fifths and more. The algorithm knob’s eleven settings further shapes the sound controlling everything from the filter, two envelope generators, LFOs, portamento and more.

70s inspired

The 1970s saw a massive expansion of electronic music instruments. Much like early electric guitars some didn’t know what to make of these electronic synthesizers. Some of these electronic noise makers were almost affordable.  (insert if you can afford a truck, you can afford a synthesizer meme)

Ease of use and portability improved as well, but MIDI wasn’t coming until 1983. Saving patches usually meant writing them down in a notebook. This was still a vast improvement from earlier interconnected cabinets in studios that needed constant tuning and maintenance and were near impossible to use live.

This era created some of the most iconic synthesizers of all time. We’ve packed the essence of 70s analog monosynth into the M3. Don’t let the simplified controls deceive you. The M3 incorporates the following:  (Synth Speak warning)

Control and structure

Three oscillators.
Three LFOs (PWM & pitch for each oscillator, and the filter)
Two envelope generators. (filter & AMP)
Voltage-controlled analog resonant filter.
Voltage controlled amplifier

Synths of this era rarely had more than two oscillators per voice. A single LFO was common. Many synthesizers use a single envelope generator to control the filter and the amplifier. So how did we fit all this 70s goodness in a stompbox? We borrowed some tricks from the 80s. As MIDI became a synthesizer standard many of those “analog” synthesizers used digital control. Analog envelope followers and LFOs were replaced with digital technology. The synth world that was still analog moved on from voltage-controlled oscillators to digitally controlled oscillators. Often the same processors found in computers were found in synthesizers controlling everything.

User-friendly for guitarists

Essentially the M3 has 121 tweakable patches. The oscillator knob selects between eleven oscillator combinations. The algorithm knob selects filter, amp and LFO settings. The parameter knob allows you to alter each algorithm in different ways.

Oscillators

Each of the M3’s oscillators are capable of sawtooth waves or pulse waves with variable pulse width modulation. One of the LFOs controls the PWM. Another controls the pitch and is used to detune the oscillators for a chorus effect.

Size & fit great
Size: Large, Color: Vintage Indigo
The fit of the jean jacket was as described. I did order a large. I am 5'11'' The sleeves were Not long they were the proper length and came to my wrist as they should have. The color was a little darker than the picture but still a nice washed-out blue. Looking forward to years of wearing this jacket. The jacket is high quality with excellent stitching. I am a consumer and was not compensated for this review.

Runs a little large
Size: X-Large Tall, Color: Antique Indigo
Awesome jacket! I am a vintage Lee Rider jacket man since high school. All Made in USA from denim Made in USA. Oldest from High School. Think I bought a Wrangler jacket once and it was not fitted like a Rider, boxy and baggy. Returned it. Wanted to try a Wrangler or Levi jacket after wearing Lee jackets for over 50 years. Modern Lee are Lee by name. After reading a 100 reviews the Wrangler reviews were consistent. The Levi reviews were all over the place, small, large, thin, thick, all cotton, stretch, made no telling where. Ordered this jacket. Ordered a XL Tall. Usually wear a XXL. But running large was a consistent comment. Sized to fit a hoodie under. Built odd, 48 jacket, 37 shirt sleeves, 36 pants are loose fit. The sized down jacket fits a little loose. May shrink down a little, washed twice yesterday. But like all Bangladesh made clothes I have owned the quality is equal to my 70’s, 80’s, and 90’s Made in USA Lee Rider jackets. The denim is top quality, the stitching is even and well done. Not as slick as my Diamond Gusset denim jacket on finishing inside, think 700.00 suit coat quality, but equal to any of my five Lee jackets. This is a Tough Wear and not an Italian suit coat. Living in Houston we only see a month or two of jacket weather a year. Wearing shorts and tee shirt today. So stores do not stock year round. Amazon was a gamble on size and quality. Looked before ordering, no stores had jackets in stock after first of the year to try size and fit. I got lucky. Fit like a XXL Lee Rider or Diamond Gusset. Quality of denim and construction are top notch. Much recommended, just order down on size if you are borderline on sizes.
