Nembrini Audio Overdrive Special Guitar Amplifier plugin is based on a Overdrive Special By Dumble* schematic #124. Nembrini Audio Overdrive Special s a two channel amplifier, which includes a clean channel and an “overdrive”channel. The overdrive channel is described as “cascading” from the first channel into, at least, one additional gain stage in the overdrive channel. This means that the clean channel’s tone stack and gain stages will “cascade” into the gain stage of the overdrive channel, causing the clean channel to become “overdriven". Nembrini Audio Overdrive Special features a 3-band equalizer and one volume control for both channels, but each channel has its own gain control. The gain controls LEVEL and RATIO interact when the overdrive channel is engaged to allow a harmonic change in gain. The Overdrive Special guitar amplifier plugin includes a complete recording chain emulation and our custom design noise gate circuit. Works as a standalone app, AudioUnit v3 effect, or Inter-App Audio effect Legal Disclaimer: Overdrive Special By Dumble is a registered trademark of Dumble.

Drikus Demo Deck — four tracks, as fast as Voice Memos. For the moment a song shows up and you need it on tape before it leaves again. Record onto four tracks, overdub without losing the take, and find the song again later — even if all you remember is one line from the lyrics. Built for actual songwriting, not just voice notes - Four tracks with arm, volume, pan, mute, solo, and live meters - Per-track three-band EQ, saved with the session - Multiple clips per track, gap-accurate — silence stays silence - Precise overdub timing, compensated for your headphones' real latency, with a manual nudge for stubborn gear - Bounce all four tracks down to one, undoable until your next bounce - Export to M4A or WAV and share anywhere - Import audio from Files, or share a Voice Memo straight in - Pick separate microphone and output devices per session Find the song, not just the file Forty sessions in, "Aug 26 · Marigold" tells you nothing. Search the shelf by a word from the title, your notes, or anything the phone heard on a take you asked it to listen to. On-device transcription (iOS 26+) means nothing ever leaves your phone — it's there to help you find the song, not to write down the lyrics. Nothing leaves your phone. No accounts, no uploads, no cloud. Your takes stay yours.
