Switch effect. Routes the guitar signal to the chosen amplifier, while the second unused amplifier is turned off to prevent unwanted interference. The gain from the instrument input to output is one (Unity Gain). The built-in buffer only converts the impedance, so that a high-impedance guitar becomes less prone to interference. When the guitar signal is switched, the speaker is switched simultaneously. Controls: ground lift, channel switching. Robust steel housing. Powered by 9 V DC power supply. Dimensions: 222 x 175 x 44 mm. Weight: 1,6 kg
