SPL Electronics TwinTube Processor RPM 500
Combined saturation and presence tube effects The TwinTube module is described by SPL as a tube effects processor to apply typical tube sound effects to any signal. Tube saturation can be regulated to add subtle to heavy harmonic tube distortions for more punch and rougher sounds. The Harmonics control allows for moving signals up front in a mix or to ennoble the top end in general with the nice touch of tube harmonics. Both effects can be used separately or simultaneously and in common. SPL recommends applications in single track processing during recording and mixing in studio as well as in live sessions.
