ThisHeavyEarth Grim v3 Overdrive Pedal
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.
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. |
| 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. |
| 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 |
| Bypass LED Brightness | Internal | Adjust overall brightness of front LED. Default setting at minimum (full CCW). |
