Instructions, Disclaimers, and Terms

Please use our Contact Us form if you have any questions about the information on this page. 

By using our products you agree to all of the terms and disclaimers at the bottom of this page. Please Contact Us if you would like a copy of these policies.


These instructions should help to guide you in installing our onboard guitar effects. These instructions are not compressive. If you have questions specific to your guitar or need more support, please use our Contact Us form  to reach us. As always, we recommend professional installation.

Working with electronics, like those found in our effects, poses the risk for injury or property damage. Please follow all safety practices for any tool, material, or equipment (such as screwdrivers, soldering irons, various cutters, and glues or solvents, etc.) used in installing or operating our effects. By using our effects, you accept and agree to all the terms on this page.

We cannot suggest that permanent modifications are a good choice for everyone. Such modifications could devalue or damage your guitar. If you decide to permanently modify your guitar, you do it at your own risk. Please use our Contact Us form  to reach us with any questions about modifying your guitar.

Tone Filters
Our tone filters can be installed with or without a switch. 

To wire a filter without a switch, we recommend wiring it directly to your guitar's output jack (as long as you have space). Connect the ground to the ground side of the jack first. Then, connect the output side of the filter to the hot side of the jack. This allows you to connect the hot signal (coming from your switch or volume control) to the input side of the filter.

To connect our filters to a switch (a mini toggle or the kind found on a push-pull pot), we recommend connecting the filter input and output to lugs one and two of a DPDT switch. Lugs three and four become the hot in (from your pickups or switch) and hot out (to the jack). Lugs five and six are connected with a jumper as shown below.

Please note: all diagrams may not represent every possible tangible component. We recommend testing connections during assembly.

Clean Machine and Mini Clean Machine

The Mini Clean Machine is designed to be installed directly into your signal path. In guitars with a primary volume control, we recommend installing it in between your hot signal and the primary volume control. 

The Mini Clean Machine can also be installed, via a mini toggle switch or push-pull pot, between your guitar's signal and its output jack as the last component before the jack.

In either arrangement, we recommend the same switch wiring as for our tone filters. Connect the ground wire from the effect to the back of the nearest pot. Connect the ground wire from the battery to the ground on your jack as shown below.

The Clean Machine, with its tone control, may require a more involved installation. 

Our most popular, and one of the simplest, involves reserving one tone knob specifically for the Clean Machine. In S-type guitars, this leaves you with a primary volume, primary tone, and Clean Machine active tone. In two-humbucker-type guitars, this leaves you with volume controls for either pickup, primary tone, and Clean Machine active tone. Guitars with four or more control knobs also have the option to isolate the effect's volume and tone, which allows for independent settings of the effect and your guitar's bypassed signal.

Upon request, we can ship your Clean Machine with a mini trimpot mounted to the effect instead of an externally controlled tone pot. This arrangement allows you to preset the Clean Machine tone while preserving your guitar's original controls. Please use our Custom Effects Order Form to order this modification.

In any installation, the switching between the Clean Machine and bypass are the same as for the Mini Clean Machine and our tone filters.

Wiring Battery ground to output jack.
Stereo shown; mono jacks wire battery ground to sleeve*.

Note: please test to your jack to confirm which lug corresponds to the tip, sleeve, and ring (if present).
*Please note, wiring with a mono jack means the battery is always connected. This shortens battery life.
Please note: all diagrams may not represent every possible tangible component. We recommend testing connections during assembly.

Custom Wiring Harness
Our custom harnesses are intended to replace all of the components in your guitar. We recommend following the general guidelines above. Should your harness need special instructions, we'll provide those to you directly.
