Surfy Industries Stereomaker




An ABY pedal typically receives the signal from a guitar or other instrument and splits it into two outputs. The StereoMaker is fully buffered and packed with features like: soft touch JFET switching, transformer isolated outputs, pseudo stereo effects, 180 degrees phase reverse and ground lift.

In STEREO mode the width and volume controls are enabled to optimize a pseudo stereo sound. The PAD switch makes it possible to attenuate line level signal to instrument level. Also the StereoMaker can be used as a direct box to convert unbalanced to balanced signals becoming a usefultool for keyboard players and recording studios.

A simulated stereo effect is generated using analog complementary comb filters. This unique implementation makes it possible to simulate the mixture of direct and reflected sound waves in a room in a very realistic way. This effect is 100% analog and safe to mix back into mono, no side effects.

Sometimes reverse phase effects can occur resulting in a “non-distinct”, “hollow sound”. The reason might be that two guitar amps has been used with different number of gain stages. The StereoMaker has a built-in 180 degrees polarity reverse circuit to phase-match amps. Just pull the output plug half way out to get the reverse phase.
