Designed to allow for more drive the harder you attack it. Play lightly for clean boost or light OD - and attack hard for more compression + drive.
The Heroine Preamp utilizes two internal circuits to recreate amp-like overdrive. A preamp circuit with MOSFET hardclipping feeds into a silicon transistor based master circuit.
Turning the master up not only boosts the output, but also starts to OD & compress just like an old amp would when turned up. Use this for 50’s era drive.
The PRE control adds OD reflective of your pickup’s output and your picking attack. Use this for 60’s - 70’s drive. If you set the PRE to max, it clicks-in a fuzzy boost - adding grit & grind with a deep lowend.
The SUSTAIN control introduces hard-clipping MOSFETs which results in a more modern + compressed distortion, taking you to 80s/90s drive.
