Classic Analog Filter / Saturator

Synth Warmer is an analog synth filter emulation based on the iconic 1970s monosynth ladder filter design, complete with overload distortion and self oscillation. Use to warm up your rude supersaws, add interest to drum loops, or create total sonic havoc as a sound design tool.

Great gain, grit, filter, and vibe plug in.

Gives everything a little warmth, some gain, grit and filtering if you so desire.

great plugin

Erik Hedin
Perfect one trick pony

Great plugin that sounds just right for the distorted lowpass-filter effect. I have used it for many years.
You just have to ask yourself if you need this plugin or if you can use your stock plugins to get close enough.

My secret weapon for mixing bass guitars

I've always struggled to deliver mixes that sound full across all speaker systems. I can create an awesome mix that sounds nice in my home studio or on my car stereo, but when I play it on small computer speakers or a tablet, the bass guitar disappears. Adding the Synth Warmer on my bass track with just a little drive adds the perfect harmonic content to ensure the bass sounds full and present on all speaker systems.

I have all their plugins except the guitar amp and they’re all fantastic!
