6v6 powered blackface Fender based circuit in a cool vintage ammo can for a manageable 20 watts of power. Loosely based on a standard blackface preamp with a few tweaks. High and low inputs with modified tone stack for slightly tighter bass. Runs a pair of 6v6 tubes in fixed bias with a 12AX7 preamp, and either a 12AT7 or 12AX7 phase inverter. Full bass, middle, treble, and volume controls with a special adjustable negative feedback control to keep the tight Fender vibe or open it up and get a little dirty. 8 or 16 ohm speaker out. Chassis is super thick aluminum made from an old street sign. Complete with the standard KO Amps magic tweaks for optimal performance.
