The Maxon SD-9 Sonic Distortion summons the sounds of the classic '80s effect through a triumvirate of a recreated knob layout, versatile tone control which takes you from boxy lows to punchy highs with a single twist, and a smooth mid-range gain. Capable of going all the way from a bluesy overdrive to vintage-voiced fuzz to full-on distorted madness, the SD-9 is an ideal candidate for the guitarist looking for classic distorted tones with a wider spread for more versatility.
