Retro-Sonic Preamp
Brands:
The Preamp is a FET-AMP (FA-1) style design offering the original circuitry updated with high quality components (metal film resistors, caps), and true bypass. It is a somewhat improved version of the Boss FA-1 FET Amplifier that the Edge from U2 has used for years.
Control layout features Bass, Treble, Volume, and Flat / Low Cut switch. As added flexibility, an internal switch can add a clipping circuit for a mild overdrive effect.
