Alexander Pedals' History Lesson gets its name from its six historic delay modes, each with their own distinct sound. Whether you're after a "bucket brigade" style delay, a vintage tape echo, or something more digital, you can achieve it with the History Lesson. This Neo Series pedal also has Tap Division controls, and a Hold button. You can further adjust the History Lesson's sound with Time (Tone), Feedback, Mix, and Mod knobs. Volume 3 of the History Lesson adds presets, MIDI, expression control, and extra functionality for each mode.
