Retro Instruments 176 Review (THE best vocal compressor ever?)
I think the Retro Instruments 176 is the best vocal compressor ever made! It combines the tone I love in a great vari mu compressor with the speed similar to a FET. It’s truly the best of both worlds to me. Check out this review and see if you agree!

Retro Instruments 176 Limiting Amplifier Overview by Sweetwater Marek Stycos from Audio Alchemist presents the Retro Instruments 176 tube limiting amplifier. The Retro 176 is a faithful re-creation of the Bill Putnam’s 176, which paved the way for the legendary 1176. The Retro 176 gives you precise dynamic control with a wide sonic range: use it to just clamp down on peaks, or push it hard to add energy, excitement and brightness. For drums and bass especially, this is an incredibly fat-sounding dynamics controller.
