Excellent condition, 8/10, price brand new is 2258SEK (about 220USD), more info: The "OptoTrem" is an analog, hand-build, highly versatile tremolo effect pedal and one of the finest studio quality tremolos in existence. The "Opto-Trem" offers you authentic sine-wave 60`s vintage tremolo sounds as well as modern square wave helicopter chop effects. Its unique circuit is carefully designed around a photocell and is very low noise. For an especially deep and homogenous modulation curve only hand-selected 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 flashing amber LED indicates your adjusted modulation speed and depth, even when the pedal is in bypass to easily match the song tempo. NOTE: The "OptoTrem" also works as a great clean boost with "Intensity" control turned down! Like all Vahlbruch pedals, the OptoTrem pedal is equipped with their unique Magnetic Transducer Button = "MagTraB" switching technology: Inside 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. The advantages: MagTraB buttons are as good as indestructible! MagTraB delivers an almost infinite number of switching cycles - many, many millions! No annoying, mechanical switch clicks! Instead, the "MagTraB" push-buttons switch very smooth and quiet
