GuitarML: The Prince

A free transparent overdrive pedal plugin cloned with neural networks.


21 November 2023

GuitarML founder, Keith Bloemer, is an aerospace engineer and guitar player. What started as a passion project has grown into a community of developers and musicians that contribute time and brainpower to make a great product. GuitarML uses machine learning and related technologies to create high-quality guitar tones. Advances in deep learning (artificial intelligence) have made it possible to play near-perfect tonal matches of real amps and pedals through a plugin. While there are many guitar plugins out there, GuitarML’s plugins are unique in that they use advanced machine learning to model the dynamic response of real amps and pedals. GuitarML is working to make this technology easy and accessible to musicians, developers, and AI researchers.

The Prince is a plugin based on Bloemer’s homebuilt, transparent ‘Prince Of Tone’ overdrive-style pedal, and was cloned using neural networks. The plugin features three GuitarML neural network models conditioned on the Gain and Tone knobs — one each for Overdrive, Boost, and Distortion modes. For the best results, The Prince should be used with an amp IR plugin to emulate the pedal’s interaction with an amplifier’s preamp. The original Prince of Tone pedal is essentially half of the highly sought after King of Tone by AnalogMan. Use two instances of the Prince for a King Of Tone-like experience!
