The Dual Professional was created for the player who requires a high power amplifier capable of lots of clean volume and “headroom” while retaining the warm, sweet singing tones of tubes. It is equipped with the 3-knob tube reverb for maximum versatility of reverb effects. The vibrato effect in the Dual Professional is of the direct-coupled oscillator type not heard from since the early 60s, giving a much different effect than the “Blackface” type tremolo, as found in the Twin Reverb®. It has 2 volume controls, switchable via the front panel CHANNEL A/B switch or the footswitch. There is also a corresponding FAT switch for each volume control, so that two separate sounds may be preset and selected during a performance. The speakers in the Dual Professional are CELESTION® Vintage 30s, selected for their clear, powerful tone.
