The devilishly warm and dirty alternative to the pure Mic Amp Module. A front end that combines classic SSL character with our new Variable Harmonic Drive circuit, delivering a time machine of overdrive characteristics.

Key Features:

• Electronically balanced ultra-high bandwidth Mic input with +20dB to +70dB gain control
• Hi-Z and Pad Switches on Mic Amp Input
• Dedicated Additional XLR Line Input
• Variable Harmonic Drive circuit adds a controllable blend of 2nd or 3rd Harmonic distortion
• Dedicated Trim control after the VHD stage
• Classic Listen Mic Compressor with fixed attack and release curves… ideal for drums
• High and Low-Pass Filters
