Quick AG is the shortcut to the perfect and natural acoustic instruments sound. It is designed to improve your acoustic guitar (ukulele, mandolin) sound instantly after selecting the instrument type.



Selecting an instrument triggers automatic internal settings accordingly to the selected instrument. That affects each Quick AG section but mainly the EQ settings. Available choices: Baritone, Guitar (for acoustic guitars with steel strings), Spanish (for nylon-stringed classical guitars), Ukulele or Mandolin.

Following knobs' base frequency depends on the instrument selected type.

Presets and more

A, B and Copy buttons - The plugin remembers 2 sets of settings, A and B. Clicking any of these 2 buttons switches between these 2 settings. The selected one is highlighted. This is a great way for A/B checking and selecting the best settings. "Copy" button copies the current settings to the other slot (if A is currently selected, the button will copy the current settings to slot B). 

The plugin comes with a set of presets, which should do the trick for most cases or give you a good starting point when tweaking your sound. Access them using the right and left arrows, or by clicking the preset field directly. You can save and manage your own presets there as well. In your computer, presets are stored in the following paths:

Installation and maintenance

Installation is a quick and simple process involving downloading and using a standard installer on both platforms, Windows and Mac OS X. The installer places the plugins and presets into proper locations so that your DAW can easily find it. The plugin is available for all relevant interfaces: VST, VST3, AAX and AU. Note that on OS X since High Sierra you may need to restart your computer to make your DAW find new plugins.

If you find yourself in trouble, please contact us via support@unitedplugins.com.


Updating the plugin to the newest version is as simple as using the newest installer.



You can either use the link to the uninstaller in the start menu by typing Quick AG for example or it can be accessed via Control panels / Applications /

macOS X

First delete the plugin files manually from :

AU: /Library/Audio/Plug-Ins/Components

VST: /Library/Audio/Plug-Ins/VST

VST: /Library/Audio/Plug-Ins/VST3

AAX: /Library/Application Support/Avid/Audio/Plug-Ins

Then if you really want to get rid of all data created by the plugin, remove the following folders as well:


HOME/Library/Application support/InstantAudio/QuickAG

Trial and activation

Quick AG is initially in demo mode, which lets you evaluate the plugin. Try it in your mixing/mastering sessions and make sure it really does the trick. When ready, purchase a licence from our shop or any of our resellers. You will receive a so-called licence file, which you download to your computer. The plugin displays an ACTIVATE button when in trial mode. Click it and select the licence file. The plugin will check the licence and activate the licence on your computer. After you restart your DAW, the plugin will be activated and will work indefinitely without restrictions. You can use the plugin on all your computers.
