Guitar Fx VST Plugins for Windows 1.1

Guitar Fx is a set of guitar effects written as VST Plugins for Windows PCs.

This shows the compression plugin

The effects are all single input / single output unless otherwise stated, as a guitar is a monophonic instrument.


These are generally simple 'building block' effects by design, and the intention is to combine several as necessary to produce the desired result.

Many effects available are complex, for instance multi-band compressors. There is no multi-band compressor here, but instead an input signal can be split several ways, compressed differently in each path, and then recombined. This is a more flexible approach, but it does require a VST host that allows connection of the effects in arbitrary input/output networks.

12 string guitar simulator
Approximately simulates the '12 string' effect on a 6 string guitar.
Two band splitter
Takes in a single input and splits the signal into two bands by frequency to produce two outputs. This is mainly used when it is necessary to apply different degrees of effects such as overdrive/distortion or compression to different regions of the frequency spectrum.
Three band splitter
As for the two band splitter, but splits the signal into three bands by frequency to produce three outputs. This is mainly used when it is necessary to apply different degrees of effects such as overdrive/distortion or compression to different regions of the frequency spectrum.
Bandpass splitter
As for the two band splitter, but the split is into a central band, and then the remainder (high and low) in the second band, so produces two outputs. This is mainly used when it is necessary to apply different degrees of effects such as overdrive/distortion or compression to different regions of the frequency spectrum.
Two signal blender
Blends two input signals together into one output.
Chorus / flanger
Produces chorus, flanging, vibrato and 'Leslie loudspeaker' type effects. Not to be confused the amplitude varying tremelo effects that can be produced by the 'Tremelo' effect.
Compresses an input signal with settable law, attack and decay, and can also produce a 'noise gate'.
Produces single or multiple echos up to two seconds delayed.
Guitar amplifier simulator
This loosely simulates the non-linear compression and frequency response of valve amplifiers.
This is a level (volume) control, with a VU display of the output level.
Overdrive / distortion
This produces a non-linear overdriven sound, and the transfer function is settable.
The opposite of blend, this splits an input signal into two output signals.
Parametric equaliser
This is a parametric equaliser: four bandpass filters have settable centre frequency, gain/loss and Q (sharpness), and there is a shelving filter at each end with settable gain/loss and frequency.
This is a phaser (for example, think MXR phase 90).
Pitch shifter
This pitch shifts the input signal up or down by up to two octaves.
This simulates room reverberation with settable room size, filters, pre-delays and feedback.
This is a three channel oscilloscope for seeing what effects actually do to the signal.
Signal generator
This generates sine, square and triangular waveforms from 100Hz to 10KHz for testing effects.
Soft clip
This generates the soft clipping 'rounding' effect of a valve amplifer as it approaches saturation.
Tone control
This is a low, mid and high tone control with settable gain/loss and centre frequencies.
This generates the 'wah wah' amplitude varying sound, not to be confused with 'vibrato' which is frequency varying and can be generated by the 'Chorus' effect.
This is a chromatic tuner operating over the range A[0] to A[6] (the piano keyboard span). It shows the note detected, actual frequency and the percentage error - being the 'distance' the input note is from what would be the correct frequency of that note.
VU meter
This shows the signal level.
VU meter (small)
As for the above VU meter, but a smaller display.
VU meter (stereo)
A two input, two output version of the VU meter.
Wah Wah
This produces the 'wah wah' sound (made famous by Jimi Hendrix) by varying the frequency band, either manually (using a MIDI pedal), or automatically depending on input signal level.

System requirements:


Download, save and then run the installer, then browse to the installed directory with your VST host application to select the effects (application dependant).
