The 30W Orange Amplifiers AD30HTC all-tube guitar amp head offers 2 dual stage channels with completely separate signal paths for convenient channel switching. The result is like having 2 vintage valve amps in 1. The Orange AD30HTC amp's Channel 1 has a thick, creamy, classic voice that barks like a rottweiler when pushed into the tone zone. Channel 2 has a tighter, springy and slightly faster character with a little more upper mids and a bit more gain. The Orange AD30HTC amp head has proved to be so popular worldwide that its specs remain unchanged. The Orange AD30HTC is quickly becoming a go-to amp head in the 30W Class A tube amplifier realm.Channel 1 and 2 controls: gain/volume/bass/middle/trebleConfiguration: channel 1/ channel 2—clean thru distortionOutput: 30 watts - Class ATubes: Preamp - 4 X 12AX7, Output - 4 X EL84, Rectifier - 1 X GZ34Very low hours, excellent condition.
