Fuzzed is an analogue modelling distortion plugin, using "state of the art" state-space modelling techniques to model the physical circuitry of the famous Jimi Hendrix guitar pedal and implement it as a VST plugin using the JUCE API.

Rather than simply modelling the general behaviour of the pedal, this plugin uses the circuit schematic to construct a highly accurate simulation of the pedal's behaviour, with full parametric control. This is then implemented as a VST plugin for use in real time.

Included are some analysis screenshots of the comparisons between the output of the system and the real pedal, which shows the behaviour of the VST to be highly comparable to the real thing.

This work is the result of continued development of a plugin created and submitted as part of an individual university project.

The examples show case the guitar tones produced, with an additional example showing the use of Fuzzed to add analogue distortion to a synth + verb as a return/aux effect.

Use of Fuzzed as a return effect can add beautiful analogue distortion to your sounds without losing the original tonal content.

**Update 14th December 2016**.

Added Windows 7 support.

**Update 2nd April 2017**.

Optimised performance on some machines. Changes to the circuit to improve the quality of the sound (especially for low frequencies).

It works fine in FL Studio 11; in REAPER 5.23, it doesn't, leaving me with this:

On simple synths, I liked the sound of it very much, so I'm eager to try it on a guitar.

Hi Vospi, .

Thanks for the download and the review.

Could you let me know what OS you are using, and also what version (x86 or 64) REAPER 5.23 you are on?

There may be an issue with the auto bridging of some 32-bit plugs to 64-bit on REAPER 5.23, (if you are using the 64-bit REAPER).

Thanks, .

Crashes Ableton live intro while scanning for new plug ins....

2 December 2016 at 1:08amVospi

The description says it's "fully tested in Ableton Live", so I think you should state your OS and DAW version (and x86 or x64, also) for them to look into.

Windows 7 home premium 64-bit, Ableton live intro 32-bit latest version.....

Hi m lopez, .

Unfortunately the plugin only works on Windows 8.1 and above at the moment! Working on the windows 7 port and hopefully have this updated in the next few days. I'll PM you when it's ready!.

Thanks for your download.

Hi, .

Just updated with Windows 7 Support.

Check it out! :)


3 December 2016 at 2:35amm lopez

Thanks didn't notice the windows 8 & up. But thank you for the update for win 7 to come....

Crashes in juce pluginhost at line 675 (newEffect->dispatchFunction (newEffect, plugInOpcodeClose, 0, 0, 0, 0)) due to heap corruption. Not always, but mostly. Tested on windows 10 x64, latest pluginhost (developer branch) win32 build.

6 December 2016 at 8:28amoxxyyd

Update: Plugin doesn't crash, it merely triggers a breakpoint stating "Critical error detected c0000374". You can continue and after a few more exceptions have been thrown, plugin appears to work.

6 December 2016 at 11:54amJPMack

Great, .

Thanks for this report and your time, most importantly.

I'll look into this as this sounds like there could be an issue with creating the circuit model when you first load the plugin.

This is extremely helpful information, thank you very much oxxyyd.

I hope you enjoy the plugin once it gets working.

Thanks, .


10 December 2016 at 3:14amoxxyyd

Any new version on the go? I'm eager to test :)

11 December 2016 at 1:32pmJPMack

Hi oxxyyd, .

Just uploaded a new version, there was an issue with trying to delete a null pointer in the destructor of the circuit class.

Hopefully should be working in Juce audio demo now.

Still no windows 7 support but I'm working on it as we speak.

Thanks for your report as this was not picked up in the initial beta.

Thanks again, .

Thanks for the new version. No crashes now. However, the gain appears to be to high. Even with both Input gain and Fuzz set at minimum, the sound still gets distorted. I think you should be able to get a clean signal with fuzz at minimum. Tested with mda epiano plugin as well as some other.

Hi Oxxyyd, .

I'm working on a dry/wet setting as personally I believe the plugin sounds very nice as a send/return effect.

The real Fuzz Face is actually a pretty harsh stomp box. It is known to distort the signal pretty heavily even with tiny input signal and low fuzz knob settings, so these idiosyncrasies exist in the Fuzzed plugin too due to the circuit modelling technique used.

The dry/wet knob, I believe, is a much needed addition to allow the user to "dial-in" the effect, rather than having it completely distort the original tone as the real pedal does.

Hopefully this sounds interesting to you and I look forward to hearing what you think when I've added this feature in the new year.

Thanks for your interest.

You're probably right about the high gain of the original stop box, haven't had the opportunity to check out the real thing yet. Might solder together one some day. But what about increasing the range of the input gain knob then?

A dry/wet knob is useful for reverbs, echoes, flangers, phaser and that sort of devices where the to signals (wet and dry) are very similar in tone and level but for a fuzz or distortion box? No I think it's a bad idea. A clean signal blended with a a heavy fuzz? I think there's a reason you don't see that sort of thing in the real world... :)

Are you simulating germanium or silicon transistors? What about switch to slect either? That would be a cool thing.

Hi! Would be great if you could check why you cant have 2 instances or more of the plugin in FL Studios plugin Patcher? (Patcher: plugin "host" type)
It freezes the second fuzzed instances gui and mutes the output? Strange problem that I never run into before. It works normal outside the Patcher plugin.

Seems to be some setting in you plugin? Do you have an idea what can cause this problem?

Thanks :)

14 February 2017 at 10:19amJPMack

Hi Mynet, .

Thanks for trying out Fuzzed. I'm really not sure what could be causing that problem at this stage, very strange. I can't recreate the problem unfortunately, does this happen every single time you try and load a second instance into "patcher" or just occasionally?

I'll look into it further.

Thanks for the interest, .


15 February 2017 at 2:35pmmynet

Thanks for the answer! I've just found the problem! It's about having the plugin window in detached mode ("external" window mode. Last option in the plugin menu)
When I tested a bit more now it's the same when you just have the plugin in a normal plugin slot when you have the plugin in detached mode (not just inside of patcher).

If you could test this and maybe find a simple solution and correct this problem in the plugin? There's thousands of FL Studio users who like free plugins and I'm sure you will benefit from tryin' to fix this :)
Thanks again.

15 February 2017 at 3:11pmmynet

I think you're into something new here that I haven't heard in any other plugin with 0 latency and with this low cpu.

Do you mind to explain exactly what every knob does? I'm very interested to hear everything you can explain about them and how they effect the outcome.

Also, if you understand why it sounds like it sounds with all the state-space modelling "module" combinations! :)

Some other questions that pop up when using this plugin:

1. Is there a eq in the algo? What settings does it have?

2. Why does the sustain increase when the fuzz knob is turned up?

3. How much direct sound is in the out signal? (Seems to be depending on the amount every knob has) At what settings is it 100% wet?

4. Do you have a chart of the harmonics added?

5. "Included are some analysis screenshots of the comparisons between the output of the system and the real pedal..." Where can I find theese?

6. Are you still working on this plugin or the new ones? :)

13 May 2017 at 11:51amJPMack

Hi Mynet, .

Apologies for the delay in responding.

1. There is no EQ in the algorithm.

2. I think the sustain may increase due to discharging of capacitors in the circuit however that is something that is up for debate.

3. The signal is fairly distorted even with lowest setting on the fuzz knob, especially if the input gain is increased. There is no dry/wet settings currently.

4. I can create a harmonic distortion freq response from a sine wave I'll try get you one soon-ish (work depending!)

5. The Analysis screenshots are just underneath the image of the plugin at the top. One contains a voltage plot for the real pedal, the other is the plot for my plugin.

6. I'm still working on this (however not full time), I also have a few others I would like to get working on, .

Thank you for your interest in this work!!.

Thank you so much for all the answers!

Another question is if you could make a stereo or M/S version of it? Now I have to use 2 plugins for stereo material.

Looking forward to new versions your working on! Good Luck.
