For an always-on, "foundation" pedal that delivers the impact of a Marshall backline, the Catalinbread Dirty Little Secret Overdrive Pedal is hard to beat. It's actually two pedals in one, with an internal switch that lets you reproduce the tone circuits of either the Marshall Super Bass (SB) or Super Lead (SL) stack. The SB mode is specially voiced to enhance your fuzz pedal's output, and the higher-gain SL mode is perfect for use with humbuckers, producing vibrant harmonics and the classic Marshall roar that ruled the airwaves for decades. And when you're ready for melodious cleans, just roll back your volume, and your sound cleans right up with vintage-style dynamics. The Dirty Little Secret has a three-band EQ, Master, and Pre-amp gain controls, and as with many Catalinbread pedals, the face displays stunning artwork with plenty of space around the rugged footswitch, so you won't need to fear accidentally changing your settings when you stomp on it.
