A glorious all analog monophonic guitar Synthesizer with Filter, Sample and Hold and Analog Chorus.

The Synthotron is an incredibly unique pedal. 

The term "unique" seems to get overused a lot in the world of pedals..... but the Synthotron III does things to your guitar sound that no other pedal can do.

From the sublime to the ridiculous. So many sounds. So many options. So much fun.

SYNTHESIZER SECTION

- 4 independent all analog voices with pitch and octave settings across them, determined by the top toggle switch on each of the four channels.
- Voice One toggle - Pitch 1 -(Yellow strip)= Unison, 1 octave up, 2 octaves up
- Voice Two Toggle - 8ve - (Orange strip) = References whichever note is being generated by Voice one and the generates either: 1 octave below, 2 octaves below or 3 octaves below
- Voice Three Toggle -Pitch 2 (Red strip) References note generated by Voice one and generates either: 1 octave below, p4 or p5 below, ma 2 or mi6 below
- Voice Four Toggle - 8ve - (Dark Red strip) = References whichever note is being generated by Voice three and the generates either: 1 octave below, 2 octaves below or 3 octaves below

- Decay and infinite sustain options - you can set each voice independently  to have an incredible crisp, staccato feel, or a gentle decay
(You can set the duration of the decay independently on each channel) or set it to an infinite sustain - where the synth will lock onto the note you’re playing and will 
only change pitch when you change the note on your guitar.

- Flux dial controls the “spring” or glissando between notes.
- Flux Toggle - right position engages the flux option. Left position disengages. Left position enables a staccato option with great tracking.

-  Seperate Dry level control.

- External Dry out (so you can split the Synthotron III between two amps - one carrying clean signal, the other carrying synth.

- External CV in.

- External Trigger in.


FILTER SECTION

- Select between - Sample Hold Mode, Envelope Filter Mode and  Manual Sweep Mode (via exp pedal).

- Velocity and Freq control the speed and frequency range of the filter

- External Exp jack for controlling frequency range with an external exp pedal when in expression pedal filter sweep mode.

- External Exp jack for controlling filter section LFO speed with an external exp pedal.


CHORUS SECTION

- All analog chorus section (based around the Empress Deus Chorus) - using a NOS MN3007 bucket brigade chip.

- Twin voice settings allow selection between a warm CE-1 styled chorus or a bright shimmery chorus

- Velocity controls the chorus speed

-  Mix controls the blend of wet and dry signal

- Depth controls the depth of the chorus effect


SUMMARY

Each of the three effects in the Synthotron III (Synth, Filter, Chorus) can be used independently or simultaneously. Three incredible, ultra dial-able analog effects in one enclosure.

Each of the three effects in the Synthotron III has it’s own foot-switch allowing ease of engaging/ disengaging each section of the pedal.

The Synthotron III is true bypass so will not impact your tone when not engaged. It runs off a standard DC 9 volt pedal power supply. Inside the Synthotron it takes the 9 volts and converts to 18 volts for maximum headroom and stability.


The Synthotron III is the most unique sounding pedal I have ever created. Synthotron I and II were unique, but also quite polarising - the inherent challenges with 
tracking meant that people seemed to either adore it or be utterly mystified by it. Synthotron III offers all the things people loved about it’s predecessors, but a vastly improved and expanded design.

This is the only pedal in the world that can create these sounds. There are thousands of Fuzz pedals, Chorus pedals and overdrive pedals. But only ONE Synthotron.
Each pedal will be hand signed and numbered by me, Ben Fulton.

Not fur Surfing or other Water Sports
I got this in a swag bag from a surfing contest. The stick is very dry...that's the only way I can explain how it feels. It certainly doesn't glide on like other face sticks. After one wave and ducking my face in the water, the product smeared off and ran into my eyes. My vision got blurry from that, and it was really hard to see the waves coming in. I won't be using this product ever again. I also looked at the EWG website, and this product was given a 6. For those new to EWG, that's not a good rating. You want like a 1 or 2.

Too little product for the price
I was surprised at how little product you get for the price. After only two weeks, the bar already broke in half, and there's not much left. Additionally, it leaves white streaks, so you'll need to rub it in after applying. I still like the fact that it's got clean organic ingredients. I won't by the bar again, but I will try the spray

Great Sunscreen — Just a Bit Pricey
COOLA Organic Sunscreen and Lip Balm SPF 30 are both really nice products. I love that they’re organic and feel lightweight on the skin — they don’t leave that heavy, greasy filmy feel that some sunscreens do. The SPF protection feels reliable, and the lip balm keeps my lips comfortable and protected without a strong chemical smell. The packaging is cute and easy to use, and I appreciate the cleaner ingredient list. My only hesitation in giving five stars is the price point — it’s definitely on the higher end compared with other sunscreens and lip balms I’ve used. That said, the performance and feel make it worth it if you prioritize organic ingredients and a pleasant application. Overall, would recommend if you’re willing to spend a little more for quality and healthier formulas!

Perfect for travel.
I LOVE Coola products so for me this was a perfect buy! The product was excellent, sizes were perfect for travel. There was item in the package I had never tried, the Radical Recovery. This product was amazing. I got burnt the first night at the beach and I used it, it immediately took away the burn. The next morning I was good to go. I used it every day we were on vacation. I even went and bought the large bottle. So if you are looking to try Coola products before you buy the regular sizes this is the perfect product for you. I was not paid or approached to leave this review. This is my honest opinion of the product. I absolutely love all of it.
