Hiwatt DR103 Custom Guitar Amplifier Head Review
The Hiwatt DR103 Custom Guitar Amplifier Head is a 100 watt, hand wired amplifier built to the original late 1960s circuit design. It uses four ECC83 preamp valves and four EL34 output valves for its powerful response. Normal and Bright channels each offer high and low impedance inputs, while the shared three band EQ, Presence control, and Master Volume make it easy to shape your tone. You can also link the two channels for extra punch and control.
