PSA1000 Analog Saturation
Not sure what’s different from the Avid version (which I also really like) but this Nembrini version is tighter, more solid in the mids and lows.
Reminds me of the original SansAmp ‘Classic' guitar pedal.
And a phase switch!
Too cool.

What a great sound! Smooth strong preamp drive, very effective eq, the master boost really warms things up, the cabinet IR's add lots of tonal options, and captures the realism and authenticity that's vital for an amplifier plugin.

The PSA1000 Analog Saturation is a sound sculpting desert island tool. Overdrive is your mix secret weapon on drums, bass, vocals, especially when it’s of the Sansamp variety. I love the sound and flexibility of this plugin.
