Stack In A Jack Distortion Onboard Effect Module

The "Stack in a Jack" does not change the tone of your instrument. It allows the full frequency of your instrument to pass through, which is why it sounds more like amp distortion. It is one of the warmest, smoothest distortions you have ever heard.

Between the Distortion, Tone and Master controls you can get any amp to come alive. The Stack in a Jack behaves as guitar amp with distortion that is fully controllable by your guitar.

If your guitar is not active or does not have a battery. You will need to install a stereo 1/4" jack and a 9 volt battery clip. See sku# H71413 for the complete Crack Potz install kit.

If your guitar is active with a battery, such as for EMG pickups or any active electronics, you can tie the Crack Potz modules directly to the same 9 Volt battery.

The Stack in a Jack is from the creator of Metaltronix and is a member of the world's first and only line of studio quality effects in a knob. Now you can get rid of that useless tone knob forever and take real control of your tone. With simple installation tools, you will have your sound at your fingertips. Your instrument is finally complete.
