Plug-in SPL^® TwinTube Processor

The high harmonic function of this plugin is fantastic - usually; on the wrong source it just makes everything worse.
The unwelcome intermodulation distortion component of the other control can only be used both sparingly and very carefully. lest it badly unglue your mix.
perhaps it's intended for master bus usage, but I think it's way to heavy handed for that.
