The FlameXS has been design out of a need for a stand-alone total clean boost; its aim is to push up the signal volume without altering the original tone or adding any unwanted distortions. Super simple to be used, it has just one gain knob. For Gain knob at 0% there’s unity volume, but it already warm up the sound, this is the reason why many guitarist like to use the FlameXS with Gain knob at minimum. The more the Gain knob is turned clockwise the more the Volume increases, up to 20dB of clean boost, without ever becoming saturated or overdriven. Thanks to its micro size, the FlameXS could fit in almost every pedalboard. The FlameXS requires standard 9V DC Negative power supply only.
