High Power-low distortion motor structure

JDI Duplex… the world's finest passive stereo direct box

The pedal was designed with guitar in mind

The XY-signal is obtained from the MS-signal by summation (X = M + S) or subtraction (Y = M - S)

Doepfer A-137-2 Wave Multiplier 2 radial High Power-low distortion motor structureModule A 137 2 is another version of a wave multiplier. In contrast to the A 137 1 Wavemultiplier I the A 137 2 generates four phase shifted copies of a VCO signal applied to the audio input. The four shifted signals are added to the original signal to obtain a fat sound similar to five independent VCOs. The phase shifting is made by a simple circuit that works only for sloped signals like sawtooth, triangle or sine, but not for rectangles or pulses
