Dont be fooled by their toylike appearance, though; these pedals are right at home on a board, with sturdy zinc alloy casings and truebypass switching. Unsurprisingly, the units are too small to house a battery (theyre not much larger than a pair of ninevolt batteries themselves!), so they rely on a ninevolt adaptor as a power source. Common features include one large transparent knob that lights up when the pedal is engaged, two smaller glowinthedark knobs, and a small button to switch in a different mode. Here, weve chosen six from the range of 10: a delay pedal, a compressor, a boost, a distortion and a pair of drives.
