About this block
Four real Pearce preamps from the mid-1980s, modeled down to the component - Green Tinted and Had Enough stock, Take Cover and Merciless carrying the celebrated "BS mod." Four amplifiers, not four presets: the differences are in the parts, not a dial.
This isn't a neural capture. It's a true circuit model, reconstructed from the original schematics and refined directly against real hardware. Each channel gets its own Drive, Bass, Mid, Frequency, Treble and Volume, summed the way the originals do - with the G1's 110-watt power section on tap, and a limiter built to keep it honest.
Features
-
Dual channel: Blend foundational weight and harmonically rich drive without compromising either.
-
Wide tone shaping: Broad, musical control that reshapes the instrument while keeping its identity intact.
- Guitar or bass: Tuned for authority and transient detail that hold up on either.
