Revered by blues, country and rock players alike, Peavey Classic amps span the tonal landscape from vintage to contemporary with ease, and the Classic 20 MH provides that tone in a highly portable package.The all-tube, 20-Watt Classic 20 MH is powered by two EL84 power tubes and 3 12AX7/ECC83 preamp tubes. It has two channels that follow the same gain structure and voicing of the Peavey Classic series amps for pure and versatile tone. The channels share a three-band EQ, lush reverb and an effects loop. The channels, effects loop and reverb are all footswitchable.Peavey's TSITM tube monitoring alerts players of power tube status, and in the event of a necessary tube replacement, identifies which tube needs to be replaced. Rear panel features such as a Microphone Simulated Direct Interface (MSDITM) with XLR output and USB out, speaker defeat switch and 3 position power attenuator switch make the Classic 20 MH mini head perfect for studio environments.
