I’ve built a nice small VST plugin in, that does nothing but emulating the tonestack of a well-known amplifier manufacturer. A short abstract of the algorithm can be found in the Research section. Again, the plugin is available for free, comments are welcome. Hopefully, someone finds it useful.
Furthermore, I’m currently working on an analogue tube guitar amplifier. The amp is almost ready and sounds absolutely great. Next step will be building the casing. Pictures will follow soon!
