The sound of so much early rock and pop was defined by the sweet chime of Vox, they sounded pretty great when people started cranking them up too. For many guitarists there is no finer amp than an AC30 for both clean and crunchy tones. Having continued to play with valves Vox have also created the Night Train high gain amps and the compact little AC4.
This pedigree has also driven Vox's amp modelling technology, perfectly capturing the sound of valves in Valvetronix and VX series combos. Eminently affordable and lightweight enough for practice and if you need something even more compact then much of the same technology drives their Tonelab multi effects and amp modelling pedals. Another option for home practice are the Pathfinder amps, sweet and warm sounding solid state combos.
