Valve Exciter

Harmonic Enhancer + valve emulation

Valve Exciter is a Harmonic Enhancer plugin with vintage valve emulation. The exciter section features hand tuned filters with the ability to sweep the center frequencies via the Harmonics knob. The valve section is modelled after a softer custom version of the vintage Telefunken ECC83 tubes with drive, triode/pentode mode and bias settings.
