A recent addition to the Matchless arsenal is the 15 Watt Nighthawk, which consists of a high-gain pentode coupled to a six position tone switch. Outright benefits include quick dial-in of new tones and an easy return to your preferred new settings. Master volume and Preamp Volume offers flexible control of the power amp section. The power amp is fed by a 12AX7 phase inverter, which drives two EL84 power tubes. This one really packs a punch!
