High saturated simple silicon fuzz that will blow you away. Features Sag pot to achieve that dying battery sound and an add-on toggle switch for selecting between the stock didoes, no diodes, and a free slot to choose with any alternative you want, germanium, schotky, LEDs, or any other diode you feel to experiment with.
The KMA audio machines fuzzy bear ™ is a great sounding, highly saturated, and simple to build Fuzz pedal that’s based on the Jordan Bosston, a black little unit that got plugged straight into your guitar, and the original effect is an absolute must-have for Pedal builders size ages. People sworn by the sound of it with an almost empty battery. So KMA decided to add this feature as an external Sag control (dying fuzz knob) that allows you to get this sound whenever you like by reducing the transistor’s voltage. Well…. there was not much to do for us anymore except adding a diode clipping switch that allows you to lift the diodes (still very fuzzy), use stock or use some even harder clipping germanium diodes.
