Model & Effects [PRO]

The Model & Effects Editor allows you to edit Performance Settings, Instruments, and Effects:

Below is a summary with links to the full help:

Performance Settings

The Performance Settings Editor is used to configure GeoShred settings such as the Guitar Play Mode, Pitch Rounding modes (Quantization), Arpeggiator, Master Rate, Preset MIDI Configuration and Tuning, Keyboard Configuration, Number of Strings and Frets, and the Guitar's Open Tuning.

Effects (Stomp Boxes)

The Effects Chain begins to the right of the Guitar in the Model & FX Editor:

Effect summaries and links to full help follow:

Mud Face Distortion

Guitar distortion effects nonlinearly transform the sound wave to generate higher harmonics and intermodulation products.

The Mud Face distortion unit is special in that it is implemented internal to the Guitar Strings, so it is always immediately next to the Guitar in the Effects Chain. It is the only distortion effect available separately for each string in Hexaphonic Strings Mode.

Hair Daze+ Distortion

Guitar distortion effect simulating the analog circuit of an early distortion stomp-box including a dual-diode nonlinearity and shelf filter.

Primal Scream Distortion

Guitar distortion effect simulating the analog circuit of a classic distortion stomp-box using a filtered dual-diode and separate tone stage.


The Feedback effect simply throws a feedback signal from its point in the Effects Chain to the guitar strings.

Volume Pedal

Volume control that is movable to anywhere within Effects Chain

Wiz Wah

Wah pedal

Dynamo Wah

Autowah: Wah pedal driven by signal level. Range, Offset, Attack, Release, and Wetness are available in the Expert menu.

Sonic Swell

Envelope follower - generates an amplitude envelope triggered by signal level that is then multiplied by the signal to shape its amplitude. You can think of it as an AutoWah for amplitude.

Sledge Hammer Compressor

Dynamic Range Compressor - more dynamic-range compression makes a flatter amplitude envelope, giving a more sustained sound.

Multi Tone EQ

Second-order low-pass, high-pass, or band-pass filter.

Moog VCF

The Moog "Voltage Controlled Filter" (VCF) provides a fourth-order low-pass, high-pass, or band-pass filter. It is based on the classic circuit by Robert A. Moog.

Geek Q

Four-Octave EQ

Four Band Parametric EQ

A Parametric Equalizer provides very general and precisely controllable equalization using elementary filter sections such as shelf and peaking equalizer filters.

Trail Blazer Echo

The Echo unit creates echoes, as you might expect.

Multitap Echo

The Multi-Tap Echo unit is four echo units in one. It is like four Trail-Blazer Echo units, except that there is no Looping, Scrubbing, or Warping, and there is individual Stereo Panning on each of the four echo channels.

Phat Phase

The phasing effect impresses sweeping notches on the sound spectrum, like the flanger. Each notch is independently created and controlled using an Allpass Filter section. As a result, for a given computational load, there are fewer but more generally controllable notches in the phaser compared to the flanger.

Mystic Chorus

The Chorus effect makes copies of its input sound and remixes them to the stereo field using differently modulated delays, thus simulating a chorus of nearly identical sound sources.

The Chorus output is always stereo, while its input may be either mono or stereo. To minimize CPU usage, place the Chorus at the point in your Effects Chain where the Effects are mono to the left and stereo to the right.

Classic Mono Flange

The flanger effect impresses uniformly spaced sweeping notches on the sound spectrum. It accomplishes this using a variable comb filter, which works by mixing the input sound with a variably delayed-and-scaled copy of the input. Unlike the phaser, the flanger notches are uniformly spaced on a linear frequency scale, and there can be many more of them at low cost.

Liquid Stereo Flange

A stereo Flanger effect.

Shaky Lady Tremolo

The Tremolo Effect is made using periodic Volume Modulation

Wiz Verb

A reverberator creates a sense of space. Classic guitar amps use a "spring reverb", which is one or more metal springs through which the sound propagates and disperses. GeoShred uses a more modern design from the field of Computer Music based on delay lines and Schroeder allpass filters

The Wiz Verb is always stereo. It is normally placed last in the Effects Chain.

Sympathetic Resonator

The Sympathetic Resonator consists of eight physically modeled strings (nylon to steel), a Sitar Bridge, and other added features. The modeled guitar can be played through the string resonator, or the string resonator can be put into a self-droning mode. All of GeoShred's tuning systems are supported for the Sympathetic Resonator.

Amp and Cab

The amplifier and speaker-cabinet modify your sound like typical guitar amplifiers.
