The Cali Dual Three Channels Guitar Amplifier 100 watt head can be driven from the most pristine clean sounds to incredible crushing wall of gain. Since the 90s it defined the sound of modern rock and metal with his distinctive liquid lead sounds. Three completely independent channels with separate controls for gain, tone, presence and volume. - Channel 1 with two voicing modes: Clean for tight and sparkling clear tones and Pushed for spicy mid-gain flavor - Channels 2/3 with three voicing modes: Classics recto mode: Raw for crunch and blues tones, Vintage for liquid and warmth high-gain sounds and Modern for heaviest and super aggressive sounds. The two different power selections the Cali Dual Three Channel Guitar Amplifier are equally important when looking for a particular sound. - Spongy works like a built in Variac, reducing all the internal voltages for atrue vintage feeling and that extraordinary "brown sound." internal voltage is reduced, making it easier to achieve an overdriven power sound, especially when the Rectifier Mode switch is in the Tube position. - Bold position, maximum power, clean headroom. The Cali Dual Three Channel Guitar Amplifier includes a complete recording chain emulation and our custom design noise gate circuit. Works as a standalone app, AudioUnit v3 effect, or Inter-App Audio effect
