The Radial Voco-Loco Mk2 is in fact a studio-quality preamp that has been carefully disguised as a foot pedal! One look at the linear frequency response, exceptional signal handling, and low noise, and you will recognize the studio quality that is built in. This ensures that the dry microphone signal will be delivered to the PA system without distortion or artifact and faithfully reproduce the instrument or vocal without compromise. A carefully crafted 2-band EQ makes adjusting the tone effortless. Turning on the effects loop adds transformer isolation to reduce hum and buzz caused by ground loops, a common problem that plagues many pedal setups. Once the loop is brought back, a tone control lets you tame the effects signal, and a dry-wet mix control lets you balance the signal to suit.
