What started out seeking the warm overdrive of the 8008 but precision tone shaping of the ST9 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.

November 26th 2023 - v3.1 - slightly modified volume for more output, fixed TS mid control is now a trim pot with default where it was set before, very subtle gain revision, newer higher quality opamps (goodbye TL072).

Controls

Name Location Description
Impedance Internal (trim) 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.
Default: 1M
Level External 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.
Tight External Pre-gain high pass to tighten up the low end.
LPF Internal (trim) Smooth out the high end of the gain output.
Default: 9/10, Almost fully CW.
Low External Cut/boost the bass frequencies.
High External Cut/boost the high frequencies.
Blend External Mix between 100% buffered dry signal and 100% wet signal
Full CCW for buffered dry.
Clean Boost Internal (trim) Adjust from unity buffer to clean boost on the 100% dry side of the Blend.
Default: 3/4 CW
Mid Internal (trim) Adjust the amount of mid hump. This is the classic Tone control and it alters the tone before going into the 2 band EQ.
Default: 8/10 CW
Bite External The mid boost control contours the frequency peak from low mids (counterclockwise) to high mids (clockwise).
Start at noon.
Gain External More on tap than the stock 808. This works in conjunction with the toggle switch.
Clip Internal [DIP] Allows for symmetrical LED (high gain punch, compressed)[on,off], Diode Lift / None (clean boost) [off,off] or asymmetrical silicon (dynamic) [off,on] clipping options
Default: Left up (LED), Right down
Bypass LED Brightness Internal Adjust overall brightness of front LED.
Default setting at minimum (full CCW).
