MST VCO is launched and ready for sale

August 28th, 2015 No comments

The circle is complete!

We are super stoked to announce that we now have the first very complete Eurorack monophonic voice in both kit and complete form. The VCO was the last of the modules that are essential to this complete voice.  Customers can now build or purchase complete this module to either make a very complete monophonic ‘east-coast’ style voice or add this 100% analog beautiful sounding oscillator to their current system. Like most of the other modules in the MST line, the VCO was designed by synth legend George Mattson.

FACTORY ASSEMBLED $239.99
KIT $149.99
PCB/PANEL $39.99

Germanium & Silicon PNP Transistor Fuzz Face Biasing Guides

July 16th, 2015 No comments

Proper biasing of the Germanium transistors found in Synthrotek’s Fuzz Face clone and the Face the Fuzz pedals is essential to getting the best (optimal) tone out of your product.  We want to take a moment here to explain how you can do this on your own for both the kit version and completed versions.  These instructions should also help with other Fuzz Face clones as well.

Synthrotek is now testing and bias testing all of the Germanium transistors that we send with kits and completed units.  We choose optimum gain for Q1 and Q2 to make sure that proper biasing is possible.  Completed pedals are biased before and after installation into the PCB to help make sure that you have a great sounding pedal upon initial use.  Even though we do this, it is important to know how to do this on your own, as Germanium transistors are very sensitive to temperature changes and will need to be re-biased now and again.  Since both kits and completed pedals both come with bias tested transistors, you should not need to completely remove the electronics from the housing.  The trimmer resistor can be dialed in by ear to suit the desired tone if you so desire.  This information is for those seeking precision.

For the Fuzz Face circuit to be optimally biased, the collector of Q2 needs to be at 4.5 volts. (When connecting the Arbiter Fuzz Face Clone circuit to your multimeter as shown in the photos below your meter will read -4.5v) The 20K trim pot is used to dial in this value.  You will need a multi-meter that reads DC voltage to accomplish this, which can be found very inexpensively at places like Harbor Freight Tools. All you need to do is connect your leads to a ground on the PCB and the collector of Q2 to get this reading. (Pedal must be powered on)

We have made two graphics below showing you how to do this for both the Fuzz Face clone (which powers off the negative rail), and our new Face the Fuzz pedal which powers off a standard 9V center negative supply and can be daisy chained with other 9V center negative pedals.

DELUXE POWER - EURORACK MODULE

DELUXE POWER – EURORACK MODULE

The MOST powerful Eurorack Power Module on the Planet.

Our new power system offers the most power in the smallest package.  DELUXE PWR is ready to grow with you as your system grows.  Start with flying bus cables and grow to our new ‘quick-release’ Molex style power connectors paired with our new Noise Filtering Distro boards.
DELUXE PWR is only 4HP and 29mm deep (very skiffable) and is LOADED with power:
+12 – 2A, -12 – 1.5A and +5 – 1.5A
We have also added a USB connector to the front that takes advantage of the beefy +5V offerings which allow you to connect your USB powered device with ease and convenience.
Our Noise Filtering Distro boards have 3 sets of noise filtering capacitors in three places on the boards to smooth out any rough edges and to help reduce module-to-module noise.
