The Chadwick delivers classic British tube amp tones with more tone and more muscle. It kranks out 50W of classic tube tone laced with incredible harmonic overtones and warmth. The Clean channel is big and fat with clarity and power and features both Volume and Gain controls so you can dial up anything from perfectly clean to a sparkly rhythm.The Drive channel features 3 gain stages (variable Gain, switchable Drive, and Volume) with a very trick Envelope circuit that creates a punchy overdrive similar to output tube distortion when turned up and an icy tight brittle sound when turned down. Both channels feature very smooth Bass, Mid, and Treble EQ controls that enhance your sound rather than change it. Any player from classic rock to hard country will fall in love with this amp fast. The Chadwick is a great match for the Revolution 4 X 12 cabinet with four Eminence V12 legend speakers.
