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.
