Looptrotter SAT 500 Series Saturator VS ST596 Saturation Processor – Comparison Page

This page compares the main features and highlights the difference between both units.

This page should be treated as the guide for the website visitors and the FAQ section.


Looptrotter SAT 500 Series Saturator and the ST596 Saturation Processor are the dedicated saturation processors designed to introduce the harmonics to the processed signal.

Although at first glance both units have similar features there some differences between them.

The first difference is in the additional Tape Emulator block which is present on the ST596 and not available in the SAT 500. The Tape Emulator feature allows adding additional saturation similar to the studio tape machine.

The next difference is in how the harmonics are applied to the DRY signal. The ST596 applies only the harmonics content without increasing the overall output level of the signal. The SAT 500 is adding some of the DRY signal along with the harmonics which changes the total output signal level.
