This Week’s Preset: Mobius – Through-Zero Flange

Posted by Pete

This Week's Preset - MobiusClassic through zero or ‘tape deck’ flanging is showcased here, utilizing the Mobius Flanger machine on the Zero+ mode.

By using a distortion pedal before the flanger, a broad spectrum of harmonics are sent into the flanger, enhancing the effect as the flanger passes ‘through zero’. The Manual parameter controls how far past zero the flanger will go. With the Regen parameter at minimum, the purest through zero effect is created.

Listen here:

The clip starts off with Mobius bypassed. The effect is engaged at 0:05. Distortion provided by a ’70s era MXR Distortion+.

Preset details:

The image below shows the knob settings and secondary parameters. Dial it up on your Mobius and give it a shot.

Pete explains Flangers in the September Premier Guitar

Posted by Ethan

Our very own DSP Engineer and co-founder Pete recently wrote an awesome article on flangers for the September issue of Premier Guitar. It illuminates some of the finer and more confusing aspects of how flangers work and how to best utilize them. Flangers can be challenging to understand … hopefully this sheds some light on the subject. Read the full article here.

Several months back our very own DSP engineer Pete Celi did a demo of Orbit Flanger for our friends over at Rock On Company.

Owen over at Gearwire recently put four Strymon pedals through their paces. Check out his demo of Orbit Flanger:

Several months back our very own DSP engineer Pete Celi did a demo of Orbit Flanger for our friends over at Rock On Company.

In this video Pete goes over the three Feedback Types (Positive, Negative and frequency dependent Positive/Negative), the three LFO types (Logarithmic, Linear and Through Zero), and demonstrates how to get a wide range of killer flange sounds.

Strymon Tech Corner #1 – Anatomy of an expression pedal

Posted by Terry

Welcome to the first post of our new Strymon Tech Corner series! I will be posting technical articles on music electronics as part of our blog at least once a month. Pete, Dave and Gregg from our team may also write an article here and there when they can get time away from their PCB layout programs and DSP emulators. Hopefully you’ll find these posts helpful and informative.

In this first edition I’ll be going through the inner workings of the common expression pedal. Once we know how one works, then comes the fun stuff … tearing them apart, modding, etc, etc. But that will be left to next month’s article :)

expression pedal from moog

We knew from day 1 that we wanted some of our pedals to feature expression pedal inputs. So, the question was “what’s the standard?” That is, do all manufacturers make their expression pedals the same way? Luckily the answer is yes … mostly.

Expression pedals work by feeding a control voltage to a device, such as a guitar pedal or synthesizer. The voltage is read by the device and then used to change some type of parameter. The voltage range depends on the design of the pedal or synth. Our Strymon pedals, for example, read control voltages from 0 to 5 volts DC. Turns out that this is a fairly common voltage range, especially in music electronics where MIDI (a 5V system) is still popular and widely used after over 25 years. The expression pedal itself, however has nothing to do with the voltage range. It’s only function is to manipulate that range and control the control voltage. The way almost every expression pedal out there works is that it takes a reference voltage from the device it’s connected to, divides that voltage down by a certain amount and then feeds it back to the device. In electronic terms, this is most commonly accomplished with a TRS (tip / ring / sleeve) 1/4″ cable where the reference voltage is on the “ring,” the control voltage is fed back to the device on the “tip” and the “sleeve” is ground.

Here  is what a standard 1/4″ TRS plug looks like:

As you can see from this 1907 diagram, TRS has been around for a long long time ;)

Here is the schematic for a typical expression pedal:

As you can see, the simplest and most common method is to use a passive potentiometer. A reference voltage from the device would enter the expression pedal jack on the ring. Then that voltage gets connected across a 10k load which is the resistive element of the potentiometer. When you move the expression treadle up and down there is a mechanical mechanism that physically turns the treadle potentiometer or “pot” as it’s commonly known. You can visualize the arrow at pin 1 of the treadle pot moving from pin 3 to pin 2 as one moves his/her foot back and forth on the pedal. This is what varies the voltage at pin 1. This is the control voltage which then travels out of the pedal on the tip of the jack. R2 is only present as a current limiter and not applicable to this discussion.

The Moog EP-2, Roland EV-5, and M-Audio EX-P all work in this manner, and therefore, work with our pedals. The nice thing about this standard design is that the control voltage is very stable and the value of the potentiometer in the expression pedal doesn’t matter so much. The Line6 EX1 is the only one we’ve see that works differently, with only a simple resistor divider and a mono cable. The nice thing about their solution is that it uses a mono cable. Two disadvantages are: 1. The expression pedal input circuit is highly dependent on the value of the potentiometer in the expression pedal.  2. Their products won’t work with other manufacturer’s expression pedals and vice versa.

Watch our video for more info and audio demos with our Brigadier delay and Orbit flanger.

I hope you’ve enjoyed this first edition of the Strymon Tech Corner. Tune in next time where we’ll make our own D.I.Y. expression pedal from a broken crybaby wah!

Happy shredding!
