- Page 2 Introduction Thank you for your purchase of the Asheville Music Tools Analoger™ series AFG-1 Flanger: a Whooshless Resonant Comb Modulator. This pedal features a reissue Bucket Brigade Delay line to deliver classic Flanger and Chorus sounds with the most natural modulation possible. The synthesizer-inspired control voltage topology provides an extended range of functionality and precision not available in most flangers.
- Page 3 Hawker’s Log: What is all this Flanging stuff anyway? History, Artwork, the Whooshless Wonder, and Flanging versus Phase Shifting The AFG-1 flanger has a rich history. It is probably my favorite delay- based sound, and is the fourth flanger I have designed for commercial release.
- Page 4 pedal, moving my feet in tandem with my picking, and felt an envelope follower would even better capture this dynamic responsiveness. In the AFG-1, the time/freq can be modulated by the LFO and by tracking the user’s playing dynamics. Using the envelope on its own removes the sometimes-objectionable whoosh of traditional LFO based flangers when not playing.
- Page 5 Hawker’s Log: About BBDs I am often asked what gives analog delay-based effects their characteristic sound. The reason for me is different than I see others usually mention. A BBD (Bucket Brigade Delay) works by storing a momentary snapshot in a capacitor isolated by a FET network.
- Page 6 With a fixed clock frequency, they can only take a sample step every 48 or 96KHz and step at that increment. This only simulates fractional delay and is not true fractional delay. The ear can hear the difference, and so the brain will process this difference as incorrect.
- Page 7 Setup For all Asheville Music Tools products, use only a standard, 9VDC REGULATED, center-negative power supply from a reputable vendor. For the AFG-1 the supply should be rated for at least 200mA. Vintage style rectified & filtered, but unregulated, supplies are not acceptable for use with this product.

Page 8: Getting Started
Getting Started Let us explore the range of controls on your AFG-1. Connect your guitar or other instrument to the INput jack. Connect an amplifier, other pedals, mixer, or DI box to the OUTput jack. If you have an expression pedal (or 0-5V control voltage source like a synthesizer output), connect it to the EXPression input. -
Page 9: Operation
Operation The AFG-1 is laid out in homage to modular synthesizers with three main modules. They are the DELAY Module, the LFO (Low Frequency Oscillator) and the Drive/Envelope Modules. Let us look closer at each of these modules. DELAY MODULE : The FREQ knob corresponds to the FREQ MANUAL knob on a traditional flanger and... - Page 10 LFO MODULE The Low Frequency Oscillator (LFO) module is a modulation source for animating the FREQ (delay time) and providing movement to the notches and valleys of the comb in the signal. Unlike most traditional flangers, our LFO provides exponential, true sine wave, and octave symmetrical modulation (instead of Hz symmetrical) for musical and balanced movement, the way the ear and brain want to experience it.
- Page 11 DRIVE AND ENVELOPE MODULES The DRIVE and ENVELOPE modules provide further shaping of your tone and control of the flanging sound. DRIVE: The Drive knob is a tweak of the highly regarded preamp and drive circuit of our ADG-1 pedal. This version provides more character, with rich saturation and tone shaping as the drive is increased.
- Page 12 CONTROL VOLTAGE or EXPRESSION SECTION: Using the EXP knob and an external EXPression pedal or control voltage with your AFG-1 will greatly increase the dynamic playing and tonal possibilities, as well as expand the control range beyond the extent of the front panel knobs alone.

Page 13: Foot Switches
FOOT SWITCHES BYPASS FOOTSWITCH: Turns the effect on or off. The LED is lit when engaged and will modulate to the LFO rate in approximately a triangle wave shape. A user accessible switch located inside the AFG-1 is user selectable for true bypass or buffered bypass depending on your preference. -

Specifications: Type: 100% Analog signal and control path • Delay Time: 0.52ms – 13.5ms typical. 0.33ms - 85ms with use of • LFO, Envelope and / or external Control Voltages Feedback: Off to self-oscillation and beyond using EXP input • coupled with knob position. - Page 15 Presets: Let’s try out some sonic ideas for the AFG-1 and lay down the comb filtering. The presets here range from classic flange to far out freak out and funkiness. Remember kids, since analog circuits have some variability, the exact knob setting may be slightly different from those shown below. Be sure to tweak to taste.
- Page 16 Talk Box: Adding Envelope control, adjust the FREQ slightly CCW and increase the ENVELOPE knob to the right to compensate. Using a fast envelope, add a little shimmer with the LFO. Place the phase switch down and increase the Drive bite to get whooshless dynamic flanging that sounds almost like a talk box.
- Page 17 Res-O-Flange: An echo-like resonance with a subtle, leslie-like warble. Tune the FREQ knob to the key you are playing in and enjoy the otherworldly, sitar-like drone. Try setting the phase to the down position to swap your sitar for a “tubular bells” resonator. Tape Chewer: Using the swirl setting, you can achieve unique textures without dominating the sound.
