If you do NOT require auxiliary power out, skip to STEP 7, below. The<br />

<strong>Acousti</strong>-<strong>Phonic</strong> <strong>Intelligent</strong> <strong>Pre</strong>-amp includes a circuit to switch on battery power<br />

when a plug is inserted into the stereo jack. If you have another electronic device<br />

(such as an active pickup system) inside the guitar cavity that requires a nine volt<br />

supply, you may power it from the auxiliary power output of the <strong>Acousti</strong>-<strong>Phonic</strong><br />

<strong>Intelligent</strong> <strong>Pre</strong>-amp. The auxiliary power output is switched on and off with the<br />

<strong>Acousti</strong>-<strong>Phonic</strong> <strong>Intelligent</strong> <strong>Pre</strong>-amp.<br />

Connect your device to the PWR pins of the <strong>Acousti</strong>-<strong>Phonic</strong> <strong>Intelligent</strong> <strong>Pre</strong>-amp.<br />

The pin next to the PWR marking is positive. The pin near the edge of the board<br />

is negative.<br />

The maximum current that may be drawn from the auxiliary power output is<br />

50mA. However, for long battery life the current drawn should be kept to no more<br />

than a few mA. Do not exceed the maximum current (in particular, do not short<br />

the output) or the <strong>Acousti</strong>-<strong>Phonic</strong> <strong>Intelligent</strong> <strong>Pre</strong>-amp may be damaged.<br />

Once you are finished installing the <strong>GHOST</strong> system you need to set up your action<br />

and intonation.<br />

Step 1: To set up your action, set each string’s height using the two Allen screws<br />

on each saddle. Once it is close, tune it up. Do any final height adjustments. You<br />

want to set the height for each string high enough so notes don’t buzz when<br />

played, but low enough to play easily.<br />
