AD50VTVOX Valve Reactor for true tube power amp sound and feel.The AD15VT, AD30VT and AD50VT feature the patented VOX Valve Reactor found on all Valvetronix products. The Valve Reactor circuit uses a 12AX7 triode vacuum tube together with an actual low-wattage tube power amp circuit, a virtual output transformer and a dummy speaker circuit that simulates the impedance changes of a real speaker. It also reconfigures itself so that its characteristics are the same as the amps its modeling (class A, class AB, negative feedback circuit, etc.) This means that all of the nuances of the original amp model including sound, feel, distortion and presence are reproduced accurately. Eleven realistic amp models using sophisticated modeling technology.A total of eleven coveted amp types are provided. Starting with the classic AC30 and ranging from vintage to modern, hi-gain to clean, a variety of amp models are built-in, giving you an incredible range of sound-creating potential. Selecting the amp model and adjusting the tone controls is as intuitive as it gets - just turn the knobs!...
