Seawell Studios Retro STA-LEVEL Review

Josh Seawell

I’m excited to share with you a review of one of my all time favorite compressors, the Retro Sta Level! It is a beast and one of the few compressors you push up to 30db of gain reduction and it still sounds amazing! By the end of this review you’ll have a good idea of how it sounds on multiple instruments and vocals.

Retro instruments Sta-Level Gold Edition

Retro Instruments, though, offer a version of the Sta-Level, which remains true to all the important aspects of the original design, while also incorporating some very useful additions.

Bettering The Sta-Level

As with Retro’s take on the Urei 176, the build quality is flawless. It combines the heavy-duty nature of studio kit from the ’50s with a few key qualities of a well laid-out modern design.
