Eternal Spring Acidic Filter

Snazzy FX Eternal Spring

When it comes to filtering, Eternal Spring is about unique as it gets. Rather than filtering a sound in line with more traditional methods, the module can sound like a wavefolder when modulated with a slow LFO, impart distinct grit at lower settings, and get extra sassy when pushed to higher settings. It is ideal for leads, basslines, and drone progressions.
