What started out seeking the warm overdrive of the TS808 but precision tone shaping to create anything from tight modern metal to fat blues grit resulted in the Grim overdrive. Mix the versatile range of tone shaping controls with additional headroom from the internal charge pump and it's off to riff city.

V1.1 will have knobs for high cut / low cut per customer feedback and the enclosure will be black on black similar to the other builds.   


  • Blend – Mix between 100% buffered dry signal and 100% wet signal
  • Clean Boost (internal trim-pot) Adjust from unity buffer to clean boost on the 100% dry side of the Blend.
  • Impedance (internal trim-pot) – The variable impedance buffer is set to 1M by default and won't matter for players using active pickups or buffered pedals in front. There is a significant impact for single coil pickups. Decreasing impedance and loading the down the pickups will attenuate the top end and smooth out the high-end grit. Pushing the impedance (default) the top end and pickup attack are more defined.
  • Bite – The mid boost control contours the frequency peak from low mids (counterclockwise) to high mids (clockwise).
  • Lo Cut / Hi Cut – On each side of the gain section you have cuts that allow you to tighten the lows or smooth the treble to reduce high end grit generated by the gain stage. If you have Hi Cut full clockwise into a dirty amp you could get squeal from the extra high end frequencies, simply trim off some of the high end. These controls allow for frequencies beyond the standard Screamers top and bottom end to be achieved.
  • Gain More on tap than the stock 808. This works in conjunction with the toggle switch.
  • Toggle – Allows for symmetrical LED (high gain punch, compressed), Diode Lift / None (clean boost) or symmetrical silicon (dynamic) clipping options.
  • Tone(internal trim-pot)  The classic screamer tone control for further control of the mid hump.
  • Treble – Cut/boost the high frequencies.
  • Bass – Cut/boost the low frequencies.
  • Level – More on tap than the stock 808. This is your standard volume attenuator that allows you to set from unity or below unity, or crank it up for a boosted signal.


    • 9V Only – Use a boss style 2.1mm 9V only power supply. An internal charge pump will increase voltage to 18V for the circuit elements optimized for headroom and reduce noise.


    • True Bypass – Soft click (1.1KGf) mechanical 3PDT
    • LED Brightness (internal trim) – Adjust the brightness of the bypass LED
