Our first limited edition pedals, the white series was a trio of pedals made with matching look and colouring. The three effects included in the series were an Overdrive, a Boost, and a Compressor. All three of the white series were created during the year 2010.

The Boost pedal is essentially a simple Mosfet transistor circuit, which adds an amount of high end clarity to your signal in a pleasant, ‘sparkly’ sort of way.

The Compressor is a simple Op Amp compressor with only a level knob to affect your signal, giving a fairly large amount of squish.

The Overdrive is a special circuit - the first successful design from JMK Pedals - is a transistor based overdrive giving a low gain sort of clear and open distortion.
