http://store.synthrotek.com/308_Euror...

"Get ready for the bright lights of the colosseum!

We've taken our rock-solid RAT clone, squeezed it into a Eurorack module and added CV control over Gain. The 308 will take your playing to new heights with tremolo and other distortion modulation techniques.

Features:
3 controls - Tone, Filter, and Drive - to customize your tone. Tone sets the brightness level, Filter dials in the high frequency response, and Drive determines the signal gain.
4 Diode Settings - An on-board 4PST DIP Switch selects between 4 different clipping diodes to drastically alter your sound. Turn on the stock version 1N4148s, LEDs, Germanium diodes, or none at all with flick of a little switch.
Vintage Tone - The PCB is designed from the original RAT tone IC, the LM308 single op amp.
Control Voltage CV Input
Guitar AND Modular - Adjust the input impedance with a trim pot.
Plug your guitar in using Circuit Abbey's Axis module.
4hp
Current draw: 10mA on the positive rail"

Keith Mcmillan QuNexus w/ Synthrotek Chaos Nand and EKO & Sequence 8 Eurorack Modules

Published on Apr 13, 2014 synthrotek·129 videos

http://www.synthrotek.com

"A super fun demo of the Synthrotek Chaos Nand Eurorack Module being controlled by the Keith McMillan QuNexus CV keyboard. The Gate output of the QuNexus comes into the SAG input on the Chaos Nand and operates kinda like a VCA, as the Chaos Nand becomes powered by the QuNexus gate, so it will only emit noise when the key is pushed. One of the CV outs (3 on the QuNexus) is being fed into the EKO CV input, which is why the delay rate is changing in conjunction to the key being pressed."

The 4093 NAND Synth is a super-modifiable noise generator that will knock your socks off with its sheer amount of sonic potential! Low pulsing drones, random robotic chaos, high-pitched laser sounds - it's all here in this small package.

A great project to begin your explorations into the world of DIY sound synthesis, the 4093 NAND Synth PCB was designed with the beginner in mind: Board-mountable switches, tension-relief power supplies, socketed IC, hands-on knobs and switches for tone control, and a detailed silkscreen PCB to help you solder components right the first time. An über-cool mod section allows for all kinds of custom control - variable control voltage input, output gating, buffering, modulation; the sky's the limit with the 4093 NAND Synth PCB.

The 4093 NAND Synth PCB was designed by our electronics engineer Steven here at Synthrotek. Powered by 9V battery, an AC Adapter rated at 5-12V 200mA Center Negative polarity can also be used."

This Video Demo features 3 of our kits / projects
A. Passive Ring Modulator
B. 16 Step Analog Sequencer
C. Synthrotek's Space Drum Synth Ds-8 clone
Check out our newest Kit for sale NOW. A classic Passive Ring Modulator. Here are the Features:

- Passive Ring Modulator requires no battery power

- Input signals such as guitar and bass may need to be preamplified

- Low part count and quick assembly. Classic 2x transformer - 4x germanium diode ring design. Schematic, assembly instructions, and Bill of Materials are available on our site.

- Selling two versions - one with 1/4" jacks, one with 1/8" jacks.

- Small size circuit, VERY SIMPLE TO MAKE - THE simplest rewards, little work big payoff. 10 Min of solder work, 5 is heating up iron

- Multiple applications - synths, drum machines, computer audio programs, guitars (may need a preamp/buffer), theremins, output of pedals (delay, for example) modulating original signal,
experiment to find what you're looking for, try different combinations of inputs and outputs for otherworldly sci-fi sounds

- The two input signals are MULTIPLIED together and produce sideband frequencies that are the sum and difference of the frequencies present in the two signals.

- Sounds like old sci-fi sound effects and produces an unlimited amount of bizarre sounds. Depending on the two frequencies

You need 2 input signals, which both work together and off each other to create unique sounds.

MANY weird sounds, by changing the inputs"

Synthrotek DS-8 Coron Space Drum Synth Clone High Def Sound Sampler

"http://www.synthrotek.com/store/clone-analog-drum-synth-bare-bones-p-126.html
The DS-8 was originally designed by Coron in the 80′s to be mounted on to a drum to in order to produce synth percussion sounds. Similar to the DS-7, which contained a VCO +VCA chain. The LFO modulated the VCO and the decay envelope is triggered by a piezz0 cell. The Decay Pot is really a release and the VCA is controlled by the LFO. The DS-8 added a colored noise generator with a balance pot, which allows more hi-hat and snare "sounds" to be achieved. This PCB is MADE IN THE USA and up to Synthrotek's fine specs. PC Board measures 5 & 5/8ths X 2 & 5/8ths inches. The Pots can be through-hole mounted, for an easy build. Kit includes everything you need to build this radical drum synth. Pop it in the case of your choice and you are ready to rip!"

Echo Quest - LFO Feedback Delay Pedal Guitar synth synthrotek effects with DS-10

YouTube Uploaded by synthrotek on Jun 28, 2011

"http://www.synthrotek.com
Brand NEW Space Delay Pedal from Synthrotek. This pedal is packed with HUGE features. There are 3 foot switches allowing maximum flexibility. The first switch turns on the delay feature with an "amount" pot and a "mix" pot, when this is switched off it goes to true bypass. The middle switch engages the feedback which can be adjusted by amount by the pot just over the on/off LED. The third switch engages the LFO feature which adds an LFO to the delay (VERY COOL AND SPACE LIKE). The LFO rate can be tuned by a pot as well as the color of the LFO (high to low frequency). This pedal is large and built into a Hammond 1590 DD aluminum case. Graphics are heavy duty and can take years of use. A very unique pedal. Made in the USA by US labor.
