—Adjusting the Gain
There is a small blue square “trim pot” on the circuit board—it is indicated by the arrow in the photo below.
This is the “gain” control for this circuit, and controls how strong the board’s effect on the sound will be.
Turning it to the right increases the effect, and to the left decreases. You can play around with this to get the
exact sound you want.

—Finishing Touches
It can be a nice addition to put some rubber or felt feet on the
bottom panel of your Psycho Box. These can be found at
most hardware stores, and can help keep your Psycho Box
from sliding around.
The photo below shows the inside of the Psycho Box once
everything has been installed and connected. Yours will
probably look different depending on the type of box/
enclosure you used, and where you decided to place the
components. We include it here for general reference.
You may want to seal your Psycho Box shut, using screws, a
small latch, box corners or some other hardware. Methods of
doing this will vary widely depending on the style of box/
enclosure you chose. Please remember that if you perma-
nently seal your box (like with glue), you won’t be able to get
in there to adjust your gain pot (unless you make an access
hole in the back).
Consider adding labels under/near your input and output
jacks to help you remember which is which. “Guitar” and
“Amp”, “Input” and “Output” or some other labels can be a
big help.
Bonus Section: Mods and Hacks
There are several ways that you can mod and hack your
Psycho Box to make it even cooler. Please note that these
are general suggestions that will require some DIY research
on your part—we do not have pre-written guides for these
things! We include them here to help jump-start your creativi-
ty and DIY spirit.
Add a Panel
-
mount Gain Control
You can desolder/pop off the onboard gain pot and replace it
with a panel-mount variety that can be adjusted from outside
the box. A 10KOhm linear-taper pot works well for this.
Add a Volume Control
