The AC Booster or "Almost Clean" is part of a trio of boost pedals from Xotic. This effect can be used as a clean boost or an overdrive in one enclosure. Being the middle child is not hard for the AC Booster because it stands out as a versatile pedal, capable of a wide variety of guitar tones. With over 20dB of clean transparent boost, you can beef up a low wattage amp or even add a touch more overdrive to an amp that sounds good on its own. Create warm tones for using the two band active EQ with +/- 15dB for Bass and Treble. Active electronics means that you can either cut or boost each frequency, further adding to its versatility.
