EVH 5150III 50W 6L6 Head is a perfect amp for players who want arena volume and performance in a portable amp. Three channels of sound cover any playing style, while independent dual-concentric controls allow for gain and volume level matching. Channel one powers clear, clean tone; channel two ranges from chunky overdrive to tight distortion; and channel three provides liquid gain. Channels one and two have dual concentric gain/volume controls, with shared EQ, while channel three has its own gain, volume, and EQ controls. The amp head includes selectable impedance (four, eight, or 16 ohms), dual parallel speaker output jacks, effects loop, headphone jack, line out, and four-button footswitch with 1/4-inch input jack and MIDI input.
