All Valve, channel-switching amplifier with ultra-transparent effects loop and valve-driven reverb. This amplifier utilises a two stage clean channel with a four stage dirty channel. The Clean Channel delivers a super rich clean tone with beautiful harmonic overtones. It is a non-master channel, much like vintage Orange amps, and when cranked the power section breaks up faster, delivering the most classic British crunch imaginable. The Dirty Channel is four stages of unadulterated filth, but it is NOT a one-trick pony. Move the Gain knob from 0 to 10, and as you do you’ll find a variety of Orange tones, from metal to fusion, rock to blues…there’s even some country in there. Controls: CLEAN CHANNEL: Volume, Bass, Middle, Treble. DIRTY CHANNEL: Gain, Bass, Middle, Treble. REVERB: Footswitchable for both channels. Features: Reverb FX Loop. Preamp: 4 x ECC83, 3 x ECC81 Output – 4 x EL34. Speaker Out: (1) 16 Ohm, (2) 8 Ohm.
