Here’s an old Cutec flanger which was modified to add a bypass switch for the LFO. This means instead of the swooshing sound the toggle switch allows you to stop the sweep wherever you’d like. It gives all sorts of filtered and metallic tones. The Depth, Manual, and Color switch function in both modes while the Speed control only works in the stock mode. This modification is available for all effects with a rate control (chorus, phaser, flanger, etc.).
