How to Replace Volume Controls on Crate XT10s
The Crate X10 is a solid-state guitar amplifier that has a built-in dual-stage gain unit that makes the amplifier a great beginner amplifier for a budding rock guitarist. The amplifier has two separate volume controls. These rotary pots, technically called potentiometers, are labeled “Level” and “Master Level.” The “Level” adjusts the level of the distortion available though the gain unit while the “Master Level” controls the volume of the sound coming from the amplifier. The process for replacing either pot is the same.
