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.

Good product.
Color: Gray, Size: 18"x24"
I live in Michigan so we have cool nights. We have hot days. Last night I went to pick up my new cooling mat to put it up for the evening and was totally blown away at how cool it was to the touch. For the price, the quality is outstanding. I will be purchasing more in the future once I know that my cats will use it. We haven't got that far yet, but once they do I will try to include pictures of them using it. I hope this helps someone as I am pretty picky about what product I buy. I was thoroughly impressed. The back side, or the warmer side is very soft and perfect for winter time use. It was an absolute genius idea to make one that is universal.

Max loves it!
Color: Gray, Size: 24"x36"
Phoenix got hotter sooner this year, and even with a short haircut, my baby kept trying to find a cooler spot. I had my doubts about whether this bed would actually keep him cooler, and Max was initially suspicious (especially after he saw the cat picture on the label). It only took one hot afternoon to sell him on this cool, comfortable lounge spot. It does feel cooler; it's a lot more comfortable than the hard tile floor and he is out of the way when on it. Good buy at a good price.

GREAT QUALITY CAT BED
Color: Gray, Size: 18"x24", Color: Gray, Size: 18"x24"
We love this self-warming and cooling cat bed because it's super soft, and the cooling side really works well! I can feel with my hand how cool it is by just touching it. I plan to put this outside in my cat's outdoor house; it will really help keep him warm in the winter and cooler in the summertime. It was super easy to throw in the wash on delicates, and I hung it up to dry. It's the perfect size, too; it should fit in his cat house perfectly and is big enough for him.

This mat works so well for my kitty!
Color: Gray, Size: 18"x24"
This pet bed is such a smart find! Someone had the smart idea to make a bed that stays cool in the Summer and warm in the Winter! The material on the Winter side is soft, snuggly plush with a foil layer to hold in the heat. Flip the mat over and it’s the perfect cooling mat for Summer, with a cooling ice silk fabric to keep cool. The mat is the perfect size for a small dog or a cat. Spot cleaning is recommended as the preferred way to clean but the listing says that it can be washed using the gentle cycle. It needs to be air dried however. My cat wasn’t impressed to begin with, but once she got a little playtime with her favorite toy and some catnip, she settled right in. This is a good mat to fit right into her crate for traveling.
