***This is now a legacy product. It will receive only maintenance updates. If you purchased Fuzz Droid using version 1.5 or earlier, you are eligible for a free upgrade to Fuzz Droid v2. You can claim your upgrade code inside the plug-in's settings menu.*** ***Please note purchases made as of version 1.6 are NOT eligible for a free upgrade to a v2 license.*** Fuzz Droid is a distortion effect based on the CP3 modular mixer. Its sharp, asymmetric discontinuity makes for a unique & aggressive sound! If you find the main circuit a little too rude, we also included a smoother curve from the same module. Finally, we took the opportunity to add some digital extras: a custom smoothing function, adjustable bias, and flexible tone-shaping filters to fine tune your sound. The result is the rudest effect we've created so far! Details: - Two asymmetric distortion circuits from OG CP3 module - CP3+: A sharp discontinuity generates massive harmonics - CP3-: A smoother curve for a less aggressive sound - Digital extras - Custom smoothing function for taming harsh artifacts - Bias control adjusts how you hit the asymmetries - Flexible high- and low-pass tone-shaping filters - Morph Settings lets you transition the plug-in between two settings. Useful for performance, modulation, automation, and more! Features: - Two-week free trial included, one-time purchase for full unlock - AUv3 effect plug-in runs in a compatible DAW - Standalone links to user manual and video tutorials - Universal purchase on Apple platforms - User presets synced across your devices - Clickless global bypass - Internal undo/redo - A/B settings comparison - High quality mode enables oversampling (plus advanced anti-aliasing techniques) - Output trim with perceived loudness matching - Global dry/wet - All parameters automatable - Optional auto gain - Mac version includes CLAP and VST3 plug-in formats Check out our YouTube: https://www.youtube.com/@sketchaudio Read the manuals: https://sketchaudio.com/manuals/ Preview audio credit: Freesound user wjoojoo
