The Milkman Sound The Amp a 50 W guitar amplifier pedal. The preamp is based around a single 12AX7 running at high voltage in a discrete Class A circuit. The tube preamp reacts with a guitar the same way any tube amplifier does: it generates harmonics and the sweet-sounding high fidelity tone that tubes are known for. Along with tube EQ, there is on-board reverb and tremolo effects so that The Amp can be used as a grab and go amplifier. Footswitches for bypassing the effects are built-in. A Class D power section delivers 50 watts into 8ohms, or 100 watts into 4 Ohms. The Speakon combination jack for speaker output takes either a standard 1/4†connection or a locking Speakon connector for extra security.
