The Peavey ValveKing 20 MH (micro head) is an all-tube, two channel guitar amp head with wattage switchable between 20-watt, 5-watt and 1-watt for different distortion and tube compression characteristics. Ideal for both the stage and studio, the ValveKing 20 MH sports EL84 power tubes for throaty distortion, versatile three-band EQ, onboard reverb, a headphone jack for silent practice and Peavey's mic-simulated direct output for cab-free direct recording. The unique "Vari-Class" control lets you sweep between Class-A and Class-A/B operation for a whole new world of tones that, coupled with the switchable output power, gives you a range of tones you'd otherwise need multiple amps to achieve.
