Smooth controls with no 'zipper noise' when adjusting the plug-in settings.
Physically modelled rotary control modes.
Separate low frequency boost and cut to shape the signature sound.
Transformer-coupled valve / tube amplifier emulation enhances the desirable vintage tone.
Innovative processing models analogue filter behaviour - without additional latency or high CPU demand.
Valve / tube emulation adds subtle character even with the EQ bypassed.*
*The EQ switch bypasses the filter section, leaving the valve / tube emulation in the signal path, while the 'power switch' provides a completely clean bypass if required.
