Alexander stuff always packs heaps into a tiny box. This has three modes, and the 'sweep' mode sounds how you'd imagine a phaser would generally sound. The 'step' mode is a blockier Optimus-prime-plays-jazz type sound, while the 'dynamic' mode increases the rate and depth according to the input signal level. Heaps of flanger to increase your level of stranger danger.
