What Peavey say about this amp:
“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.
