APX 351 Black Friday pricing from Tone Empire is 67% off, which puts this preamp plugin at $19 until Nov 25, 2026.
It is a preamp plugin, and the maker says it reproduces the warm, harmonically rich character of a well-known preamplifier from the past.
The maker describes the sound as analog warmth added to your recordings, with a vintage character and real sonic depth. Tone Empire also calls it a very rare and sought-after sound.
Harmonically rich is the key phrase there. A preamp stage like this adds harmonic content to whatever you feed it, which is why preamp plugins sit early in a signal chain, on a track insert, before compression or EQ.
APX 351 is a VST3, AU and AAX plugin, so it loads in any host that supports one of those formats.
The plugin uses an online license registration system. In trial mode your computer has to be online to run it.
Once the plugin is registered, you no longer need an internet connection to use it.
