Pigtronix FAT Drive is an all analog tube sound overdrive. The FAT Drive’s multiple cascaded gain stages enable you to nail sounds ranging from bluesy overdrive to rich saturation, all while retaining musical dynamics and the original character of your instrument.
FAT Drive takes a futuristic analog approach to create complex crunch tones using CMOS clipping and a variable low pass filter for tone shaping. Bringing the tone control all the way clockwise takes this filter completely out of the circuit for total transparency and robust low end. Rolling the tone control back smooths out the highs, leaving ample mid-range bloom and bottom end punch.A Hi / Lo toggle switch brings additional versatility to the FAT Drive’s wide-ranging palette of overdrive tones, altering the gain structure for enhanced crunch and soaring leads. The FAT Drive features true bypass switching and runs fine on standard 9-volt power but ships with an 18-volt adapter for superior headroom, clarity and overall output.
