The Custom 20 takes its inspiration from the Renegade combo, but strips back the feature set and puts it in a bigger box with a Celestion G12H-75 Creamback speaker to produce what could be well be the loudest 19 watt combo ever made. And if that's all too much the Variable Headroom control lets you take the output power down as low as 2 watts so you can run the amp breaking up at a volume to suit any situation.
