There are two ways to install A Little Thunder, both are considered simple and straight-forward:
1. A direct-to-jack 5-minute Quick Start diagram #1
​
2. Multi-pickup setup (most common) Click here to view the simple diagram #2
For each, you will need a soldering iron, solder & a small screw driver. Please note you will also need a stereo cable to produce the bass signal. We recommend this $12 stereo Y-Cable from Amazon or this upgraded $40 one from Sweetwater
As always, we're here if you need us through the support form and typically respond within the hour.

MULTI PICKUP SETUP
TIME REQUIRED: 15-20 MINUTES
-
Remove your old pickup (heating up existing connections on your pickup selector & volume pot with a soldering iron to loosen them).
-
Solder white wire (guitar signal ‘hot’) of A Little Thunder where the old ‘hot’ connection was on your original pickup & do the same with the ground, where it previously was soldered to (A Little Thunder's ground is the green wire).
-
On your old input jack, take off the existing guitar “hot” and guitar “ground” connections. On A Little Thunder’s included stereo jack, solder green wire (ground) to the middle tab and the white lead (guitar hot) to the right tab on the stereo jack.
-
Lastly, the black wire from A Little Thunder (hot bass) goes directly to ring tab on stereo jack (see diagram below)
Be sure to use our recommended TRS-Y Cable mentioned above or a single 1/4″ stereo cable. If you don’t have one handy, you can use a mono cable and pull it halfway out of the guitar’s jack. You will get both bass + guitar signals, but they will each be 50% faint until you use a stereo cable.
