Its unique circuit is carefully designed around a photocell and it shows super low electronic backgroundnoise. For an especially deep and homogenous modulation curve only handselected photocells are used for the \"OptoTrem\" and each pedal is hand-trimmed to this specific opto-cell. The \"Speed\" and \"Intensity\" knobs control modulation rate and depth, a toggle switch allows to select either a \"hard\" or \"soft\" modulation curve. The pedal output level can be adjusted using the \"Volume\" control. A constantly fashing amber LED indicates your adjusted modulation speed and depth, even when the pedal is in bypass to easily match the song tempo.\u003cbr\u003eNOTE: The \"OptoTrem\" also works as a great clean boost with \"Intensity\" control turned down!\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\u003cb\u003eThis pedal is equipped with their unique \"MagTraB\" switching technology:\u003c\/b\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eInside the button a magnet is integrated which position is measured by a sensor on the circuit board. If the button is now moved, e.g. if it is pressed downwards, the position of the magnet will also change. The sensor measures this change without any mechanical contact to the button and the information is send via a micro-controller to a gold-plated relay, which then does the actual audio signal switching.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\u003cspan\u003eThe advantages of \"MagTraB\" footswitches:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul type=\"disk\"\u003e\n\u003cli\u003eMapTraB buttons are as good as indestructible! \"MagTraB\" delivers an almost infinite number of switching cycles - many, many millions!\u003c\/li\u003e\n\u003cli\u003eNo annoying, mechanical switch clicks!
