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.

Absolutely Essential for Any Athlete or Gym-Goer!
Size: Large, Color: (035) Steel / White / Black
I recently purchased the Under Armour Unisex-Adult Training Cotton No Show Socks 6 Pack, and I must say, they've become an indispensable part of my workout gear. Here's why these socks are a game-changer:
Comfort Above All: These socks are incredibly comfortable. Made from a blend of cotton and synthetic fibers, they provide just the right amount of cushioning without feeling bulky. Whether I'm running, lifting weights, or doing yoga, my feet feel supported yet free.
No Show, All Go: True to their name, these socks stay perfectly in place without slipping down into my shoes. This is crucial for maintaining a professional look at the gym or during sports activities. No more embarrassing sock peeks or having to constantly adjust them.
Durability: For the price, these socks hold up remarkably well. I've washed them multiple times, and they haven't lost their shape or elasticity. They've survived the rigors of both my workouts and laundry day.
Breathability: The material mix allows for excellent breathability. My feet stay dry and cool, reducing the chances of blisters or discomfort during long sessions.
Pack Value: Getting six pairs in one go is fantastic. It means I always have a fresh pair ready, which is perfect for someone like me who works out frequently.
Fit for All: These socks fit true to size and are designed to be unisex, making them a versatile choice for anyone looking to upgrade their sock game.
If you're in the market for socks that combine comfort, performance, and style, look no further. Under Armour has nailed it with these no-show socks. They've quickly become a staple in my wardrobe, and I find myself reaching for them over any other sock I own. Highly recommended for anyone serious about their fitness routine or just wanting reliable, high-quality socks.

Excellent athletic socks
Size: Large, Color: (100) White / White / Black
Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too.
Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.
