BJF design high headroom overdrive with adjustable low/mid EQ balance.

Hand-made in Finland premium quality classic blues/rock pedal that works very well with complex ovedriven amp sound.

It's a low compression, high headroom overdrive with high output, and it has a Body knob for adjusting low-mid content and treble.

As designer Bjorn Juhl put it:
Whereas Little Green Wonder is a TS-style pedal, but one for those who don't generally like TS-style pedals.
Big difference between these two pedals would be headroom, distortion style and distortion depth and treble response, output level, function of tone knob, color, symbol....they do share a common layout of mechanical components.
