This paper describes the theoretical background and the source-code of a software plugin emulating a tube amplifier for electric guitars. The circuit 5E3 of the Fender Tweed Deluxe amplifier is used as the base for the amp model.
Some circuit variants and a universal tone stack extend the tonal range of the original circuit. In contrast to existing comparable solutions, this plugin runs in real-time even on fanless tablets, with very low latency, and with plenty resources left for the obligatory IR-loader and an armada of additional guitar effects, if required.
The sound quality and the playing experience is at least on par with existing solutions. The models for the tube stages are based on real tube circuits but are simplified as much as possible without sacrificing aspects relevant to sound and playing experience.
The plugin format is JSFX. The JSFX script may be loaded into the VST3 or AU plugin YSFX provided by Joep Vanlier, or it can be directly used in the digital audio workstation REAPER by Cockos Inc. YSFX is available free of charge for Windows, MacOS and Linux.
Included JSFX plugins :
360 Degree Panner
Blender
TWD DLX
Volume Wah
Load VST3 or AU in your DAW and load JSFX plugin with UI’s load button into VST3 or AU
