Classic plexi to early 70s Marshall Super Lead and Super Bass sound and response

Marshall amps helped supercharge the performance, and shape the sound of rock and roll. When the house lights dimmed, all you could see through the hazy darkness was the array of red pilot lights shining from a backline wall of Marshall stacks. It was the ultimate prelude to the impending rock. In the absence of your own personal wall of Marshalls and the necessary road crew required to lug them around, the Dirty Little Secret (DLS) is the perfect secret weapon in your tone arsenal. This is your “always on” pedal, designed to be the "foundation" of your pedalboard, transforming any amplifier into those raging British stacks. It forms the core of your guitar sound which you can enhance and embellish by adding boosters, fuzzes, filters, and other overdrives in front of it - just like you would in front of a real amp. And the reason you can leave it always on is that you can get a great clean sound just by rolling back your guitar's volume knob! That's the way the old school Marshall players did things!
